That’s as I expected; Thanks for confirming.
Unfortunately, that leaves out the kind of integration I was asking about (and the kind implied in this post), through existing Qt & KDE shared libraries and such.
CopperSpice might still be interesting for stand-alone projects written in C++, though, and I appreciate that you’re here engaging with the community.
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.
