Welcome to the great open community, glad to hear Qj is doing swell...
Hi PSP767,
Welcome to the M for Mature community! Please don't hesitate to let us know of any suggestions or issues you may have by posting in our Feedback/Help forums.
To answer your question, there is a post by Abe Froeman that details why all the staff from QJ (or most of them, anyway) decided to create M for Mature.
Hope you enjoy your stay!
Didn't I make your avatar wayyyy back when, in the Qj days? When I was The_PSP_Playa or Neilstheman?
