i'm very new - so new it makes me wince. i spend a lot of time looking for answers before posting here. i try not to do it until i really feel like i have nowhere else to look, or i just can't get the concept. people are so generous with help. so to make sure i'm not being lazy when i ask, i have to pay in situps before i can post. the dumber i am, the flatter my stomach will be. i appreciate this resource very much and don't want to abuse it, but i also realize that one of these days i'll be able to help someone else, so i don't feel so bad.
