Within a thread (topic) posts can already be moved to a different forum: that's handy if a post raising a particular issue needs to be moved to a more appropriate forum.
However, it'd be really neat if another type of “topic shaping” could be implemented: by allowing posts within a topic to be moved to a different, already existing thread / topic.
That's handy, for example, when someone inadvertently (incorrectly) opens a new topic with a post (eliciting subsequent responses) that really should have been added to an already existing one. There's presently – to my knowledge – no way to “fix” that, other than simply locking the new one (and perhaps manually adding an advisement to continue replying in the “old” topic).
Just an idea. 
PS: I'd let either the post date/time decide where exactly in the existing topic the moved post would go, i.e. in the event someone added replies to the existing ones, so that the posts are in chronological order, or simply put them in the old topic in the place corresponding to the time of the edit, i.e. to avoid “interjecting” within an existing exchange. Both (either one) of these approaches would work fine for me.
Um… If it turns out that it's already possible to move a post to a different topic… Um, my apologies; I simply couldn't find that.
