There’s a particular kind of topic that I feel existing forums don’t do a good job of addressing. These topics (which are often pinned) have a first post which is more of a document than a discussion-starter, and the content of that message isn’t really “owned” by its author.
I think a better model would be for the first post to be a sort of wiki page: editable by anyone (or if locked, by moderators only); and displaying only the most recent information (but preferably with viewable history).
For example: #cythera ! - Ambrosia Software Web Board
The original poster of this topic hasn’t been active in years, but last year, the IRC server that we’d been using since 2001 was shut down (shocking!), so we moved and a moderator edited the post to point to the new server.
This is a progress log. Several forum members are responsible for updates, but updates have to be funneled through the author (who is not a moderator).
A rules topic. There’s one on this forum too, but it’s hidden behind the menu icon. I find that an unnatural place to look for that kind of information (but of course what I find “natural” is informed by long-term forum use).
