Who's behind this conference?

This event, just like all other ADASS conferences over the years, is run by volunteers contributing their free time. Sponsor companies and institutions contribute financially and/or work time of their employees. Conference profits go entirely towards a fund helping cover costs of future ADASS conferences.

Will there be any other social event?

We hope so! We are looking at organising visits to the city and the Alhambra among other activities. Please check this site for updates.

The CfP will open sometime in late spring.

Is there a support program for speakers?

We do not have an extra support programme for speakers.
Please apply to the Financial Aid Programme.

Speaking at the conference

Registration, speaker / participant profile handling etc. is handled by our technical secretariat. Please refer to their site for how to edit your profile.

How can I edit my proposals?

Abstract submission is handled by our technical secretariat. Please refer to their site for how to edit your proposal.

Can I add another speaker to my proposal?

Yes, before the close of the CfP you may add another speaker to your proposal. After the review: No.
There should be a good reason for having more than one speakers for talks, please state in the notes.

I have submitted a talk, but would like to make some edits after the CfP.

Please feel free to make reasonable edits and improvements to your description any time. Regardless, your talk must not become a different one. Changes are monitored. Please note during review the talks are non-editable, once accepted you may edit again. See "How can I edit my proposals?" above.

Presenting at the Conference

We do encourage everyone to use gender neutral language at the conference.
Please make sure to bring a HDMI adapter with you.

Are speakers invited to the conference?

Invited speakers will be provided a complimentary ticket for the conference but we do not cover any travel or accommodation costs.

I have updated some information - but it does not reflect on the website.

We use a static website. All information is coming from the registration database. The website updated approx. once a day. Please be patient.
Please do not write to help desk to request information changes, it's self-service, thank you.

What about internet during my talk?

There will be no guaranteed internet for the talks, try to avoid making your presentation depend on internet connections. Use internet at your own risk. Though we try our best, conference WiFi performance might not meet everyone's expectations.

Other Options to Present About a Topic


Birds of a Feather (BoF) sessions are participant-driven conference spaces dedicated to topics of interest to specific communities. BoF organisers are invited to submit a proposal for their BoF session.


What about student tickets?

Students must present a valid student ID at the conference. If you are a student or will be a student while the conference is running you are eligible for one student ticket. In case you are a student now but won't be a student in November we cannot offer you a student ticket.

I'm on a budget and cannot afford a ticket.

Please have a look at our financial aid and scholarship program.

Can I pay ticket by invoice?

No, purchase via the website only, which requires a credit card.

The credit card is not working, are there alternative payment methods?

Yes, we do offer bank transfer as an alternative payment method. However, if your credit card is not working, please do contact your bank. This is a recurring issue with North-American cards when your bank was not notified of a possible foreign purchase.

Where can I find the invoice?

Once the purchase is finished you will receive an email from Eurocongres with your invoice.

Can I order tickets via purchase orders?

No, tickets are sold exclusively via the website. If you like to see more service consider sponsoring the conference.

Sorry for this, but we do not accept purchase orders for tickets, please buy via the website.

No, we do not offer discounts.

When are you going to start selling the tickets?

Ticket sales will open sometime in spring. Please check out site for updates.

How much are the tickets?

Ticket prices are going to be in line with last edition figures but are not set yet. Please check this site for updates.

Ticket prices VAT

All ticket prices include 21% VAT. European regulations define that conferences are taxable in the country where the conference takes place, so the EU VAT reverse charging mechanism cannot be applied. However companies can easily apply for a VAT refund from the authorities.

Are tickets refundable?

Yes, tickets will be refundable until approximately one month before the conference, no refunds after that date. Administrative fees are, however, never refundable. You may re-assign the ticket to someone else if you cannot make it or donate it to the financial aid programme. Please send an email to the organisers to request a refund, refunds will be credited to the credit card used for purchase only.

How can I change information on my badge?

We will use the information you provided on the registration page for the conference badges. If you want to change what is on your badge, please contact the LOC.

Conference badges will be printed upfront, please make sure all information is in place by then (approximately one month before the conference). Any changes after this date won't reflect on the badges.

No, we don't offer any extra discount codes.
