there at the top above every other thread!
how did you create an account and make a new thread without seeing all the threads with the word sticked.

Guys, why are you replying to this person's question in this forum. The proper response is:
"This forum is for administrative and non-laser help, and as such, your questions are in an improper forum. Please take these questions to the Tutorial and Help forum, and do some reading around the forum."
