If you know someone who has played here in the past, where are they? Why aren't they here? I really could do to have the feedback as to what's keeping them away, or why they left.
Better yet, ask them to come back. There is maybe one person who has left us over the years that I absolutely wouldn't want back in game, so please; shoot them an invite. If they have reservations, tell them I would love to talk to them about it.
This is not just to help the site. This is because we have a great deal of friends who aren't here any longer and really, friends are able to overcome whatever squabbles have happened in the past.
