Calendar File Form: Roger Bell_West has set up a site which converts this page to standard calendar file format, and updates that file periodically. See http://firedrake.org/infobot/ics/conventions.ics for this. Or - I'm told that by using webcal://firedrake.org/infobot/ics/conventions.ics instead, you should be able to "subscribe" to this calendar. Note that I haven't looked at this since this page changed URL.
28th-29th June: Longcon, at The Garrison Hotel, Sheffield. "An RPG convention for all weekend games. ... Welcome to Longcon, a tabletop roleplaying games convention for long form games that will last all weekend. Fancy a change from high pace 3 hour slots where you finish and want more? Longcon is for you. The organisation of the convention will be a little different, as the all weekend format needs to support people making good choices and organising groups that will play well over the full weekend." Membership rates don't seem to have been set at the time of writing. Watch https://longcon.ttrpg.uk/ for more information as it emerges.
