Huh, seasoned writers! I like you already
Also, the trick around here is to get away, not getting to stay! LOL
Well, to answer your question - I'd strongly recommend sticking round here too. I write romance, PROPER romance (very flowery, and little death, lots of luuuvvvvvv) and I found a place here. Granted, it's historical romance, so it does fit this group a little bit, but other than that, I have very little in common with the fantasy powers, magic stuff, etc., and it doesn't matter one bit - I have learned a lot from this group and have received valuable feedback and help.
I have no idea how active the YA group is, but compared to some of the other groups around here, this group is by far the most active (that I know of). Everyone is great, warts and all! (see what I did here with the warts .... LOL) But unless it gets too hard to manage two groups (and it might be if the YA group is as busy/active as this one), I'd say join both!
Also, if Amy throws a rock at you, don't take it personally, it just means she missed K! 
I'll check you novel out - I have been reading a few YA novels on the site, so it's not all foreign to me. And soooooo, do you read romance at all?
