My question about the forum macro is how closely is it maintained along with the Confluence code base? I ask this because of my experience with Builder. I installed Builder for my Confluence instance a few years ago and now I have about 30 separate wiki spaces depending on Builder for the layout of their space. I am at a university, so I have very small windows of when I can upgrade my Confluence instance, and I'd planned to upgrade to Confluence 3.1 in January. However, I was told that a Builder plugin wasn't ready for Confluence 3.1 and wouldn't be, for a few more weeks (we need a window of about a month to test everything, before the upgrade date). So basically, I missed one upgrade window.
Now I'm being asked to install Community Bubbles and the forum macro. So I have this fear again. I understand that a forum can be just a part of a wiki whereas Builder really controls the entire wiki, but I have no idea if someone might make their entire wiki space be a forum, so if a similar thing happens in the future with a macro/plugin upgrade not being ready for the Confluence upgrade, I'm stuck again.
So this is where I'm just trying to get a little info on whether my fear for this forum macro being similar to Builder in the way described above is reasonable, or if there's some reason that I would never run into this problem with Bubbles and the forum macro?
