Talk to Llamaman or Big Dave. Small chance you'll get the image done unless it's virtually perfect... but good luck. You have some amazing signatures so who knows.
If you are talking about a logo for the website, I don't know. If you are talking about a logo that says "Admin" no. If i'm not mistaken they are working on one along with the new site layout.
Hey Buddy, I suggest getting rid of your sigs... they aren't YOURS lol... And no, GR doesn't need a logo.
Just run with it and say it's the logo so they stop asking US the members... Maybe ask an admin... who can actually answer...
