There are quite a few features the vbulletin has, like there is a car showing what percentage your PM box is at so you know when to empty it, also on each thread there is a post #...like this thread I wrote is post 1, the first response to it is post # 2, then the 3rd is post # 3 etc...That is cool to have for the few long threads we have.
Please look into it

refer to www.bimmerforums.com for more info.

Thanks,

Also that little line on top in the main page that tells you that you have pm, like the old i-club.
