Default Re: Hello guys

If you are going to become a fairly active member here, I'd like to recommend you are vetted by a forum veteran of your choice. We've had a banned member come in and continue to make new member identities, due to this, all new members are suspect to me, until someone can confirm you aren't him coming back for more games. Interested?

Hang around and let us get to know you, we've had a lot of trolling lately and a LOT of new members in the last few days, very unusual activity. Please allow yourself to be vetted as a sincere member by a vet of your choice.
