Join consequent posts

[Nicolas]

Ability to setup delta time, so consequent posts from the same user will join.
It will prevent non-informative several posts in a row from the same user.

I think this is plugin territory. In my forum I have several threads where only admins can post updates for users. Not really a discussion topic, more of a change log or mini blog. If posts were to start merging the updates would get tangled.

Just one use case, but I'd prefer the core code not to automatically join double posts....or at least make it an option.
