Indeed, but I was more talking about a Lemmy community where people would be able to discuss and give each other information.
I actually stumbled upon someone asking a question on Reddit, it could have been interesting to have a place to redirect this person to: https://old.reddit.com/r/Lemmy/comments/1dtj4hc/can_anyone_help/
The alternative is a Matrix room, but it might take some time to set up compared to just a community on another instance
Sounds great, thanks!
