Infoboxes are largely a known issue. The basic deal is that infoboxes must have class=infobox in order to get them to slide to the right. But because our infoboxes have class=infobox=exterior to create the nice, rounded, shadowed shell, and class=infobox-interior to create the, well, interior, it's confusing the prototype code. The result is an interior that's trying to be aligned with an exterior which isn't there anymore. instead, it's now a blue puddle underneath the infobox. Basically, base prototype code had split the infobox apart. It's an easy, if repetitive, fix in which the interior will have to get a new class name.
The issue of the Recent Wiki Activity (RWA) module being on top of the infobox is also something that's well known, and which the Engineering team are actively considering. Just out of curiosity, how many here find the RWA useful? Not talking about the placement here, but rather the actual content of the module?
