A web forum is far better in most cases. If you can't manage to run your own, there are plenty of lemmy servers that will do it for you. Even an email list (with searchable archives) would be better than Discord.
If you have collaborative documents that outgrow the forum format, use a wiki.
If real-time chat is needed, irc or matrix.
A project hosting its community on Discord is a project that won't get my contributions.
I recently went through these exact pains trying to contribute to a project that exclusively ran through Discord and eventually had to give up when it was clear they would never enable issues in their GitHub repos for "reasons."
It was impossible to discover the history behind anything. Even current information was lost within days, having to rehash aspects that were already investigated and decided upon.
It's the "see no evil" approach. If you didn't report the issue while the admin was online, then they aren't compelled to do anything about it. Convenient for the project maintainer who doesn't actually like maintaining things. Awful for the rest of us.
It's sad when a web forum is better than the tool you're considering. Bumps, aggressive garbage collection, no Resurrection, it's weird.
I'm old, I guess. I miss NNTP, mainly for the archived posts I could discuss with the authors for an updated take or revised solution or some clarification. And yes, I know there's a good webUI front-end for an NNTP server as a back-end. ;-)
