I was wondering if anyone can provide some pros/cons of "Blaine's Forum Plugin" versus "PhpBB". I was wondering if more features are available in the phpBB, perhaps. I'd like a spell checking option, but I didn't see one available on Blaine's script. Or, perhaps there are other forum options for Geeklog???

There is a thread on a comparison:

The question is not so much on how many features there are but what you need personnaly.
