Off the top of my head udolipixie, sparrow24, robotic, and knowmeyourself have good advice/answers and questions. There are too many to name though, I like a lot of people on here, that's why I am here lol(:
I like so many people here because I like reading their questions and/or answers. ^_^
I know I am forgetting quite a few names (now that I am trying to remember on the spot) but these are some of the users I really enjoy: Robotic, Janson, MrOracle, Sparrow24, Kambo_Trick3y, Prof_Don, Cottoncandydreams, and Confucius16.
I tend to admire answers by Prof_Don, Sparrow24, Confucius16 and I think Robotic has some pretty unique questions. Prophecy hasn't been around in a while, I always found his answers quite funny, but they still give insight. SensAsianalGirl is a little spunky at times but also gives good answers even though she is relatively new. I know there's a couple others, but sleep deprivation prevails at the moment and their names aren't popping up in my mind at the moment.
