First Alienware experience and a question

Hi all-
Aurora R4 owner since April and pleased with it...she purrs like a kitten. I read in another post a reference to the alienware arena and wonder if that site is a sister site or somethin'- I won a tact-X keyboard from there- and was a seamless integration into this R4. I try to search to answer my own questions but am on meds and kinda old...
Anyway- hello AW-ers
