That's awesome! I haven't been contributing here for a while, and I wrote the last blog post stating if more than three users wanted it to continue, I would do it. But I'm looking more forward to your questions. I'm really happy this wiki is starting up again!
I just removed the Base-3 ~ Base-9 columns completely from the infobox. At the same time, I set them up in a way that if there's a leftover parameter, it will display a category, something like (Pages with leftover parameters (Base-x) so that tracking them can be a bit easier.
Anyone can revert vandalism and bad-faith edits, but it takes a couple of clicks in the page history to get it done. Users with the "rollback" permission are able to undo bad edits with one click, by using the rollback link on diff pages, user contributions list, or the list of recent changes.
It is important to note that admins (including bureaucrats) already have rollback rights by default. Users with rollback rights are just users who are not necessarily an admin.
Rollbackers (users with Rollback rights) can be seen via Special:ListUsers, but they do not by default have any special title that appears on their userpage.
