I've never used it, i have another program i use that works for me so it's what i know however one awesome thing i see is graham is on a lot of sites and i have never seen him unwilling to help anyone.
I have not used it, but have quite a few close friends that have and they swear by it. Like someone else mentioned, Evan is all over the internet and willing to help anyway that he can from what I have seen.
It is great! Plus Evan commonly frequents this forums and many times is willing to answer any question you might have about his program, which is I think is pretty awesome. Plus he is a super nice guy.
