Any other comments or questions for us?:I would like to keep the green period. It's what some other GT members used in 1.2, and I know it's still recognizable to GT members; Zeyphr knew that's what it meant. If it is an absolute necessity that I take off even the green period to join Fk, I suppose I could though. 
Thanks for reading!
Forgot to mention this earlier, you can definitely keep the the green dot (:
If you make it into Fk|, the only required thing you have to have in your name is the Fk| tag. Other than that, you have total creative freedom of how you color and decorate your name.
