There will be an online version of BiCon using Zoom.
It will run for at least two of the three days, Saturday and Sunday. See the programme pages for the details, but the likely timetable is:
Saturday
Sessions starting at 10:15, 11:45, 14:30, and 16:00. They'll be a lunch break at 13:00.
Sunday
Sessions starting at 10:30, 12:00, and 14:15. They'll be a lunch break at 13:15.
There'll be a break of at least 15 minutes between sessions.
There may well be an online social space on Saturday evening. If so, it will use Discord, and you'll get an invite when you book.
Tickets are priced on a sliding scale, as ever, from £4 to £20.
