As you'll have noticed, the forum has had a significant makeover. There were a number of problems with the previous theme that I used after the forum was upgraded. This theme is based on the standard theme provided by the SMF developers so it's been tested more and is more compatible than the previous theme.
I hope you like the new look. I think most things work the same as the old theme. One or two things have moved around. If there's something you can't find please ask in Chatter and we'll try to work out where it's gone!
