Rotating signatures periodically is encouraged, not required.

I have a question:
Can I chose any of the signatures in the OP without any restrictions, also the one that is called "Contest Winner code"? thanks.
-BM-
Yes, since you're a Senior Member (or higher). Full Members may choose any of the first three. Also, signatures are in the first reply, not the OP, but we all know what you mean!

The Contest Winner code was the result of the new signature contest that I ran last week. There isn't anything different about it for the purposes of the campaign; you're free to choose what you like (or try them all on!)
Thank you for taking time to explain it to me in detail, I was uncertain of the last one was reserved for somebody who won a contest....... the last one is my personal favorite, looks nice, I can almost smell vegas.
I will rotate them as suggested. Peace!
