Now im not raggin on MyBB, but this is like IPB and vBulletin all put into one, so, its kind of like getting vBulletin and IPb put together eh? But i heard it was easy to skin, so i decide, hell why not try it out, and maybe make a skinning forum...but good looks so far people
And it's getting better too
MyBB Gold is to include a heck of a lot of features that the others call extras...
And we're all waiting patiently for it to be released...
Like IPB/vBulletin but better
And it's free, which gives a pretty big advantage over both those two :p
(wrong forum by the way)
Personally, I still don't think MyBB is good enough to be equal to IPB or vB, but it's certainly getting there. But, without a doubt, it's way better that phpBB and just about any other free PHP BBS.
