For feature details, visit Whova
  • Our Whova site is online!
    • As you have already registered, you should soon receive an automated email notification from Whova about the opening of GECCO’23.
  • Whova can be accessed with a web browser (Chrome recommended) or using a mobile app from https://whova.com/portal/gecco_202307/?source=download_page
  • To access GECCO’23 using Whova, you must use a Whova account with the same email address as the one you used to register.
  • If you already have a Whova account that uses the same email address as the one used for conference registration, you should already be able to enter GECCO’23 in Whova. Otherwise:
    • If you don’t have a Whova account, follow these instructions to set one up: https://whova.com/portal/gecco_202307/
    • If you have a Whova account associated with a different email address, please follow these steps:
      • From the Whova mobile app, you can edit your email by clicking on your profile on the top-left corner, then 'My Contact Info & QR Code', and then 'Email'
  • Once you enter the GECCO’23 space in Whova, you should have full access to all available functionalities, i.e. agenda, list of attendees, messaging, sponsors, virtual meetups, and more. In particular,
    • The Whova agenda allows you to browse the schedule and access live sessions.
    • When entering a session, you’ll be given the choice of watching it in your browser or using the standalone Zoom application. In our experience the latter tends to work better (and allows changing background, while the former does not).
    • To ask questions and interact with the speakers, use the Whova chat associated with a given session (not subsession). The Zoom chats are intentionally disabled. In regular sessions, you can use your mic too, but please adhere to the guidance of the session chair.
    • Consult our Guide for attendees for more details and recommendations: https://gecco-2023.sigevo.org/Guide-for-Attendees
    • Please notice that the pre-recorded videos will become visible in Whova only shortly before talks.
  • See the Whova Attendee User Guide: https://whova.com/resources/how-to-guide/user-tutorial/
  • Use the ‘Ask Organizers Anything’ feature to inquiry us about problems, or preferably use the contact email address indicated in the GECCO 2023 Help section below.

Gather access details

  • Gather is open.
  • To access gather, simply
    • follow the link above.
    • password: provided in the email each registered participant received or on Whova (see Organizer Annoucement: 'Access credentials for Gather').
    • Note: these credentials should not be shared with those who don’t attend GECCO’23.
  • Gather is organized as a 2D virtual space where you have an associated avatar that can interact with other attendees
    • Please customize your avatar (using Edit Character button) to make it informative to the other attendees, i.e. use your full first and last name in the ‘Name’ field.
    • If you are not familiar with Gather, we highly recommend visiting our Gather space prior to the conference and learn about the controls and features of this platform.
  • Gather allows you to access all sessions by following the dedicated Whova links available in the corresponding virtual session rooms.
    • Please familiarize yourself with the different Gather spaces.
  • The Poster sessions will take place in Gather.
    • Presenters are encouraged to stand on the star next to their posters in order for participants to better identify them as presenters.
    • Each poster is identified by specific coordinates. The list of posters and their coordinates is available in each poster room.
    • The zoom level and viewport of the poster is controlled by each user independently and thus, two different users can see different parts of the poster. You can use the “visible click” tool to highlight points in your poster. This tool allows you to highlight a point in the poster by clicking on it. The audience will see those clicks.
  • If encountering problems in Gather, please visit the Help Desk located near the entrance, and
    • Talk to the producer/volunteer if s/he is available there, or
    • Read the instructions by approaching the paper icon and pressing ‘x’, or
    • Fill the inquiry form that appears after approaching the envelope icon and pressing ‘x’.

Voting for Best Paper Awards

  • Voting for the Best Paper Awards will be realized using the LimeSurvey system hosted by SIGEVO. Each registered participant will receive a personalized email with a link to the voting page. Please be warned that such emails tend to be occasionally redirected to spam folders.

System Requirements to Access Virtual Platforms:

  • Web access:
    • Any state-of-the-art popular web browser, however, Chrome is recommended for best experience.
    • Zoom Application
  • Mobile access: Whova app, available on iOS and Android
