That’s a good idea!
I’m not familiar enough in Brussels to suggest a location outside of FOSDEM, while the venue itself is crowded enough to make it not reliable to meet in a specific room or restaurant (with especially the restaurants in the F-building spread over multiple floors, bars and rooms adding confusion).
Is it maybe handy to use one of the Yunohost-Matrix rooms? Preferably not a high volume support chat, or else the meeting requests will get drowned. That is, I’d swear I’d joined a support room, but I don’t see it in the ‘Rooms and spaces’ under Yunohost :
Any suggestions?
