It's something completely different.
This project started in a Discord server, which was originally used for all kind of discussions regarding organisational matters and with regards to ideas, how our software should be structured. At some point, a chat became unuseful for that purpose (because of the temporary-ness and live-discussion-nature of chat messages), so someone set up that forum. It's still in use for these three types of discussions:
- How should our project be organized?
- How should our software look like and work in general?
- Where should our project be headed to?
Then we launched our first community: Writing. It had an assigned "Meta" site (something that became a Meta category recently) for discussions about their site and site policy. Naturally, some bug reports and feature requests were opened there, too, so it became an place for that kind of stuff, too.
Some time later we opened this Meta.Codidact site for discussions about aspects, which relate to more than one Codidact community. As with Writing.Codidact Meta, bug reports and feature requests were opened here, too.
This means, that these kind of things are somehow accepted here, too, as long as they are more about questions of detail and not about the grand scheme of things. You can -- of course -- suggest the latter here, too, to rally support within the live communities. That will be a priorization factor for the organization of the development effort. (And if you want a feature desperatly, why don't you build it? :D)
Because the forum uses a completely different software (Discourse), there is currently no joint user account. An other sign for that is, that the organizational matters (as the forum) are on codidact.org, whereas the communities are on codidact.com.
At some point in the future, it may be a good idea to either use the forum as an OAuth provider, or to build an OAuth provider into our software, so that you can use codidact.com accounts there too.
