There will be a BiCon Gather running all weekend (and indeed all the time, it's always available). We'll run a couple of specific drop-in sessions for chatting, but you can pop in whenever you like. The link will be provided to registered attendees.
Gather is an online social space best accessed via a laptop or PC, though it does work on phones etc. You navigate it by using arrow keys and pressing X to interact. If you'd like to get a feel for it, this is a public Gather space you can wander round: https://app.gather.town/app/kbzCxWG7iH0filHH/KingstonLGBTQGather
The screenshots below should give you some idea of what to expect from the Gather space at BiCon, although there's really no substitute for trying it out yourself.
