Proper Use of Series

This issue came to my attention a while ago, but hasn't yet been addressed. It seems there are quite a few empty series here on the site. What a series is intended for is to link together related stories. So, here's the rules: you cannot have a series with only one story, or none. If you intend for there to be more, wait until the other stories are posted until you create a series. And, lastly, all stories in the series must be written by you (unless it is an open series).

These rules are going to be applied retroactively, since series don't give a creation date, so I'm giving everyone one week from this moment to either delete them or add something to them.
