Just saying, since all browsers support css3 and xenforo is very compatible with all major browsers, and the features they're creating, I have a feeling as a php developer, xenforo is about to become the most used forum software in the world. I have a feeling in 2-3years (If the developers continue to create more features) that are actually useful like how they made the Warning System in the last patch. If they continue to make more useful features, this software will be 1 big big hit, (Not saying it is not now) I am just saying I think it will grow even bigger. 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.
