Like I said I love Ubbthreads but to name a few a built in calendar,posting buttons and scripts way superior to what we have now in 6.0( image buttons ) a referer system to refer members so you can run contests and track the status through a users profile All kinds of features it goes on and on. You can add modify upload anything from the admin page ( smilies,avatars,code, etc etc ) These are all things you can add as hacks in Threads but are standard in Vbulletin. However like I said much harder to configure as their templates are great but harder to edit as they are threaded and broken down into every aspect. It is about 70 bucks cheaper to own and member area support is only like 30 bucks a year. I decided to own both. []/forum/images/icons/wink.gif[/]
