The problems starts when i want to move someone's post from a thread into another existing thread. In that case, the movable post (message) is going and sit at the first position of the existing thread destination renaming, at the same time, the author of the thread with the author of this particular post. How could avoid that? When i move a post in an existing thread, i want always to go at the last position of existing posts.
And something else, can i change the post positions in a same thread? F.e. #5 post to move it in #2 and the #2 to #5?
