I don't have a firm timetable but I will probably be upgrading the forum sometime tonight, as there is an upgrade to the forum script and theme available. When everything goes right, this is an unobtrusive thing, although there is sometimes a brief period where the forum will go offline while files are being updated. I don't expect anything to go wrong but I suppose it could happen. There is no need for you to do anything in particular, as you probably won't notice it. I just wanted to mention it in case you were in the forum when the updates began.
