helpful hint to the newer user.....
alot of people on here won't answer basic questions. ALWAYS try to find out the answer to your questions thru already existing threads before you start one. no one has answered you because the sticky noted threads have this info and so does about 20 other threads in the catfish form. do your research first before asking. then if you have a specific debate among info then that would be something that is maybe worth answering.
no one told me this when i started until i talked to a friend who was familiar with forums. so here is your curtousy. check previous threads for the info you want to know before starting a thread.
at the top of each forum/ thread there is a button that says search. use it.
Good luck!
