Participants and authors are spread out across the world. This is by far the trickiest aspect for virtual ICLR. Most of us are not used to navigating across timezones. The calendar displayed on the website is shown in your local time, and the Google Calendar with all the events is public and can be copied to your personal calendar.
Here are some hypothetical interactions from hypothetical people across timezones:
On Day 1, April 27, all videos for that day are released at the start of the day (GMT+12). This includes the pre-recorded PC welcome, two invited talks and the 5 or 15 minute videos for the papers in the poster sessions for that day.
A participant Maryam from Syndey (GMT+11) decides she would like to join two poster sessions, one at 5 am GMT and one at 8 am GMT (4 pm and 7 pm her time). Earlier in the day, at 10am, she starts by watching both invited talks and posting questions on RocketChat. At noon, she visits a few booths: one on a discussion about optimization, and another for AwesomeCo since she is interested in an internship. At 4 pm, she joins the 2h poster session, browsing posters and joining the Zoom link for posters to listen & ask questions. InvitedSpeaker1 lives in Kenya and has a live Q&A at 5pm Kenyan-time (2 pm GMT). Invited Speaker2 lives in NYC and has a live Q&A at 3 pm his time (7 pm GMT). These happen while Maryam is sleeping, she will watch these recorded Q&A on April 28.
Meanwhile, Marek from Lagos is waking up (GMT+1). He has planned to join the live Q&A for both speakers, and the poster session at 12 GMT (1 pm his time). Then he is going to go to a social being held on RL in the evening, at 5 pm. He starts the day, at 9am, by watching the first invited talk, and writing down a few questions. He then watches a 1-hour oral/spotlight session on RL, with two 15-minute orals and several spotlights. He finds this by clicking on the sessions, which can be watched at anytime that day. He joins the live Q&A with InvitedSpeaker1, at 3 pm, and Raises his Hand on Zoom to ask a question (and is then called on to ask, with his audio unmuted). He then watches the second invited talk, and Thumbs Ups a question that was asked by another participant on RocketChat. That live Q&A happens at 8 pm, but he cannot join in the evening. He watches the recorded Q&A the next day, and the question he upvoted was asked and answered.
Linli from Seattle is waking up. They marked 10 papers they would really like to investigate deeply. They start by watching all the videos for those papers (9 of them have 5-minute videos, 1 is an oral that is 15 minutes). They also watch three other videos from the set of papers recommended for them. They join two poster sessions, at 5 pm GMT and 8 pm GMT (10 am and 1 pm their time). Fortunately, 8 of the 13 papers they watched videos for are in these poster sessions, and they can chat with the authors. They know the live Q&As happen at 2 pm and 7 pm GMT, which is 7 am and noon in their time. They decided to watch both videos the day before (on Monday), and post a question on RocketChat about each. They tune in to the second live Q&A, at noon right after the first poster session they attended and right before the second one.
Throughout, Participants have discussions (asynchronously) on RocketChat and can post written questions for the authors on the channel for their paper. Authors pop in and write answers to questions for their paper.
