I run ikonboard gold still and it's been great The situation there isn't great but the board a stable full release version, easy to customise and set up too. The new "version" of ikonboard will be php instead of perl so it'll be a lot faster. It's being made seperately to ikonboard though as the creator has left ikonboard completely but will be making a converter which will allow you to swap over to the new board if you want to.

I'd still recommend ikonboard
