passwords

We have been having some trouble with members in our forum giving out passwords. Going to other forums and inviting people that are not members of our forum. So our members are complaning this is not fair. Really don't understand why they do this . To make them feel special on the other fourms ( maybe ). We have been working very hard at making Drawdead freerollerz.com a great forum. The players that do play in our private freerolls and are not members will not be paid.
