Question for #Fediverse experts: There's a new community I became a part of that communicates primarily through a #Signal group atm.
Pretty good (#Whatsapp is still the standard here) but they're not completely happy with it. One of the reasons I heard was that they'd like some way to organise #events, hold #polls, distribute #files and other info..
Is there a #Fedi #platform that offers these things? Or would something like #Nextcloud be a better option?
