Due to problems with /mail, I have resorted to posting a forum post. All listed players (with a picture of your property) must come on the server in the next 2 weeks for you will be evicted and your build removed. List of players:

You can always post a sign on their property letting them know the time limit as well. I know that many players don't regularly come onto Enjin or the forums.
