I kinda agree with Hiltz.
At some definition, the Scrambler is a specific 'trim level' of the Bonneville.
High pipes, etc, but the "guts" are the same (although timing and tuning may vary) so it would make sense they are discussed within the same "folder" of the forum.
A separate Scrambler folder probably wouldn't get much traffic, since those guys have already been hanging in the BOF, or, there would be duplicate posts/threads in a Scrambler forum, so I don't really see why Scrambler specific threads can't stay in the BOF. It's not like there is a bandwidth issue, and those of us with Bonnie's that are interested in Scrambler discussion have only one place to look. Seems like this is a non-issue, unless you count the disruption of moving a post from BOF to TT.
Of course, this is just my unsolicited biased opinion, so, YMMV, $0.02, caveat emptor and all that good stuff.
