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.
Once again, I'll be doing some upgrades in the background tonight, so there is a possibility that the forum will go down for a short period of time; probably not long, if at all.
The software upgrade is completed, without trouble. I'll be upgrading the style and some of the our plugins but that shouldn't cause any problems.
Sometime tomorrow or tomorrow night, I'll be updating the script for this forum, as well as a few other behind-the-scenes stuff. During the process, there may be a brief period of time in which the forum will be inaccessible, but I don't anticipate any problems with it. Past updates have been easy enough.
Actually, I didn't get to it yesterday. With the move to a new web host, I didn't have all of my FTP information together.
