Splitting a topic

[ladyinthemists]

Can you split a thread when the posters get off topic? For instance, say the sub-forum you are posting in is titled "Movies" and your thread title is "The First Wives Club" for members to discuss that movie in particular. Then someone else comes in and starts talking about "West Side Story" instead of "The First Wives Club." Can you, as Admin, split the topic so that you can start a new topic titled "West Side Story" and move all of the posts about that movie to the appropriate thread instead of just leaving it in the "First Wives Club" thread? This getting off-topic can really be irritating at times when they go off in totally different tangents and lose the original intent and purpose of the thread/s. Any ideas or suggestions? Can this even be done??
