@imix4u thanks for the Birmingham suggestion!
The best way to get a certain place added as a forum in the community is to do exactly what you did - request it here! We are working on a new way to display locations so they're not in a super long drop-down menu. We'll add a bunch of new locations once that's done!
For events you'd like to post now that don't have a "home" board, just make sure you reference the specific location in the subject line and add the location as a label within your post!
