I have the reprint - July 2008.
It takes a moderator to move an existing post to another sub-forum. But it probably doesn't make a huge bit of difference here, as it's still quite a small forum.
Just have a little look at all the sub-forums on the home page, then pick one thats fairly close.
Good luck with the build, the bimmer is a decent motor to use, German quality and all that
