In my opinion we're not ready to go "invite only" just yet.
First we need to get a more solid group of members.
I would say that 8 active, skilled (sp and/or mp wise) and loyal members should be our goal right now.
I'll see what I can do, but it's hard to find someone to invite.
I would be amazed if the four of us successfully invited one player fit to be a part of the solid group of members that I mentioned.
