I should be getting a vBulletin license soon for 4.X and that means we can use 3.X as well, so I thought I'd make a poll asking what you think we should use!
Please note: it's not about which one is newer, if you don't know what's different please have a look before voting
It's been a while since i've used a forum with vBulletin, but I'm in favor of 4. A comparison would be great, if there is one. I tried to do a search, but I couldn't find anything. I did read that a lot more people prefer 3, though.
I like the stability of 3 in my browser, but I like the ability to connect via my iphone with 4. I voted 3 because stability wins over mobility for me.
