Dear GCF 2021 poster presenters,

please email your poster (main document & thumbnail document) to us at no later than June 8 at 1 pm UTC (= hard deadline) following the instructions for the format.

Posters will be presented in dedicated poster sessions and also displayed in the GCF2021.Town, which will be activated on Gather ~ 1 week before the conference.

Gather.Town sessions will take place each day 30 minutes prior to the official start of the conference as well as at the end of each day.

Participants can join the GCF2021.Town on Gather in a 2D world with 8-bit graphics, walking around the virtual conference venue by moving their avatar with their keyboard’s arrow keys. Please note that an avatar marked “anonymous” or carrying an invented name such as e.g. “007” does not get interaction, since participants are looking to interact with other participants. We thus encourage you to use your full name.

When creating your poster, please follow these guidelines.

We strongly encourage you to also post your poster on our conference GCF 2021 slack channel which will open ~ 1 week before the conference.

Details on how to access both channels (Gather.Town and Slack) as well as respective links will follow soon.
