How do you even find specific communities this is the closest thing I found to r/help for lemmy

https://lemmyverse.net/communities

Watch out for rule 5: no how to questions.

But, for your question, I search using the search function on my client, eternity. For many smaller communities, they're not going to be active.

!support@lemmy.world is a better place to ask for help.

edit: there's also !lemmy_support@lemmy.ml which might be better, since the one above is lemmy.world specific.

I also found !lemme_help@lemm.ee, which seems specifically for general Lemmy help questions, but isn't too active.

I use the search feature in Jerboa
