Ok, so one build version stops messages from posting if they contain apostrophes and the latest misses out the first letter of usernames if you use the dreaded combo of Win 7 and IE8 - it doesn't actually matter because this mod is so sweet.
It runs like a dream and the config options in the back end on the latest version are neither too many nor too few but just right. It installs really simply and easily also.
Support via the forums is fairly good and certainly prompt, the author clearly knows his stuff and cares deeply about what he does.
Frankly, I'm surprised this mod is non-commercial.
