Re-order Posts

[Googa]

I think it would be amazingly userful to be able to re-order the posts within a thread (in linear mode).

For example, on my forum there are many times that a thread creator will make a thread showcasing artwork, and then attach more artwork to another post in the same thread at a later date. Because there's normally replies between both posts, the new work usually doesn't get as many views... especially if it's pushed onto the next page. It would be nice to have the ability to post that second post as post #2 in the thread.

Here's an example of a thread where this would be helpful:
http://flux.rant-on.net/forum/showthread.php?t=129
(note that post #6 would become post #2, and the current post #2 would become #3, #3 would become #4, and so-on)

Yet another thread where this would be useful:
http://flux.rant-on.net/forum/showthread.php?t=5

If anyone has any idea how something like this could be implemented, please let me know!
