Actually, I don't moderate here, I'm just kind of mouthy. See, I've done beta reads, and more times than I've received gratitude or a suitcase full of cash I've received an email that said, in its entirety, "Thanks!" (Plenty of times, I've had no response at all.) To me, this is not enough for the ten or twenty hours I gave the person's book, unless I am positive s/he is going to pay it forward, doing a beta for someone else.
New people hoping to snag that many hours of my time and whatever expertise I may have are not getting it. Not because I'm a selfish bitch but because I don't want to do such a huge favor for a stranger who doesn't even try to become part of the community but instead dives in asking for what serves his or her needs, before giving anything at all.
Now, I expect you're probably just eager (and maybe a little scared?) and didn't mean to present yourself this way. This happens all the time. So no one's holding the request against you. But I sincerely hope you'll make the effort to become a part of the AW community before asking for so much from it. As I, and everybody else, gets to know and like you, and sees that you are offering critique and beta reading for others, I bet you'll have no trouble finding what you need. That's how things most often work, here and elsewhere.
(BTW, AW is going to be down this weekend, so that's writin' time. See
