Old splitting method.

[Blind Guardian]

My forums (forums.gamewinners.com) are running on 3.5.0. Basically, my moderators have been having to adjust to the new method of splitting threads since we upgraded from the old version. Having to go through every page and select all the posts is time consuming in forums that get a lot of traffic (I advise my moderators to split threads at 100 posts).

Previously, it'd take me all of 5 seconds to load a thread, split out the posts and post in the old one with a link. Now, having to load at least 3 pages just to select everything, it'd take at least 20.

Is there any way that the old method could be incorporated? Preferrably in a plugin or some such, as I simply run the forums for the owner of Gamewinners.com meaning he alone has access to the server any file-edits would have to be applied by him, and let's just say he's not terribly active when it comes to the forums and their growth.

Any help will be appreciated.
