What differentiates this forum software, compared to vbulletin, or IPB or SMF?, is that this software is amazingly faster. I mean go look at some ipb 3.2 sites it's slow as snails, then compare those features to xenforo and then compare a speed test, xenforo blows it away. Also ipb 3.2+ devlopers keep making features that become useless/slow down the site, xenforo has been making new features (like the warning system) that are "not useless" and actually useful on your everyday life as a Admin or a user.
So kudo's to xenforo, this software will be the most used commercial forum software in the world. In about 2-5 years, It will be bigger then vbulletin and ipb combined.
Take my word for it.
Good work guys.
