I agree with what Kanebear's proposing in the above post. Stickies are not useful in this scenario, in my opinion. While I think there should be flexibility between forums in terms of the degree of OT that's allowed, I don't think it's useful that threads which would be ON topic in another forum are posted elsewhere (eg UK destination specific threads in the BA forum). I think having the sub-forums where relevant would help people to post in the place which is most useful to the most number of people without creating too much inconvenience in terms of altering current posting patterns.

ETA: I also think that destination specific threads should not be in Travelbuzz, but in the forum for the relevant destination.
