Yeah, moving it to a top-level board is no issue, although I'm not sure exactly how it would help (since it's already a seperate sub-board).
As for the time and date thing, I'm not convinced about that, honestly, for a couple of reasons. Firstly, it requires us to actually explicitly work out how long every post takes, which is a pain. Secondly, it causes serious problems when groups get out of sync. Right now, if I'm in a group that has been doing something that should logically take an hour and you're in a group doing something that should logically take 10 minutes, we just overlook that (it happened several times in the first CE, particularly with Rider). If you have an explicit date written, then it becomes impossible for the two groups to interact until they are in sync (which I suspect is unlikely to happen very often), which tends to force us into seperate, non-interacting groups a lot of the time.
As for location, I guess giving that might make sense, although it is a bit more hassle, again, because it means actually explicitly working out where you are.
