Easy. It's so the GM doesn't have to dig through pages of OOC posts to find the sheets. It doesn't mean he's going to pick the first one he sees.

As a GM I always find it easier when it is in a new post so it is easier to find. Rather than it being a placeholder someone telling me they finished there sheet and me have to go trawling for it.
