If there's an application thread and the applications start coming in, there isn't an easy 'Move This Post' Button.
You have to go into the Moderator Control Panel, then split the post from the topic, creating an entirely new thread in the process.

From there, move the entirely new thread to the archive that is in another board.

Why not just have a button that would make would be similar to the split topic function

Move post button, exactly like the split topic function, but skip the step of creating a new topic/thread in the same forum, rather being able to place where you want the new topic/thread of, checked applications in this case.

Just an suggestion to help speed up cleaning old posts, thanks for reading.

Also, adding an option for creating posts. Being able to center, right or left column would be a helpful option as well.

Hello,
Head over to your ACP (Advanced Admin Panel) and click the 'Posting' tab at the top. Select 'BBCodes' on the left hand side' and scroll to the bottom of the page where the pre-set bbcodes are. Click 'enable' next to 'left', 'right' and 'center'. Now a bbcode will show for the alignments when creating a new post in the full post editor.

As for the move post button, it isn't a bad idea, but I don't think it would be used enough to justify implementing it into the sytstem. If it is something you absolutely want, you could consider upgrading to Avanced Hosting where you'll be able to make the appropriate file edits.
