Scattered to the four winds probably Mickle. A few probably migrated to STW I remember seeing something from one of the refugees about a new forum they had started on CC somewhere. MBUK will have taken over the MTB sections of BR with their textspeak.
You are missing out. Actually once you get over the navigation issues the forum is very good. What I like most is that I can go there and click on "Post since your last visit" and 99% of the post that come up are cycling related.
It's quite good for training and nutrition issues, although it doesn't have the corps d'esprit that this place has. Also, I don't know who any of the members there (and in the first days,a good few of us left due to heavy handed mods), whereas over here everybody knows your name. And you're always glad you came.
