Self-Hosted Main

Kind of wild watching this open source chat run out the open source corporate endgame but I never thought they would enact as severe user limits as they now have done for the free self-hosted plan.

25 might be fine for family chats but for non-profits or event-based chats; the latter my thing where a handful of people coordinate throughout the year and then 30 to 50 (more?) are around during the event week, this is the end.

I thought for awhile that the 25 limit was going to apply to a free-hosted-by-RocketChat basic plan but 6.5 self-hosted has the limit as far as I can see so... there we go.

My options are:

1. Stick with the 5x series. I never moved to 6x at all when they started adding app/plugin limits for the free versions - that kinda made me a bit sus of what was to come.
2. Mattermost, which is fine but I'd lose 8+ years of events. Someone has a converter but right now that's a non-starter due to the size of our loadout and the basic early-days nature of the converter. Could always keep the RC instance going for archive purposes I suppose.
3. Matrix, which honestly, tempting...

Looking for anyone to chime in with other options/opinions if they see/know any.

EDIT: A user post suggests upgrading RC to the 6x line forces a license change that puts you on the 25 user limit path but it can be reverted back to the Community Edition with a conf change. Would still like to hear your opinions though as RC is clearly on a pre-determined path at this point.

EDIT #2: Just an overall thanks! Lot's of great responses both on my stated options and new ones I did not know about. Keep'em coming!
