Wait, do 2011 joiners count? I hope so, because I second the aka nomination. B]
Also, if that's the case, I could totally nominate Dr. Mc (2011), right?
And
Lige? He hasn't talked much on the forums, but I've talked with him via PM and he's really chill. I think he has great potential. :] He also joined in 2011, but he literally hasn't spoken on the forums until this year.
And also, threeofspades still qualifies for this (2012), but she's not exactly on the forums anymore. Maybe she will return someday, but I dunno. ;_;
