Come on, you've at least got to give details about what the story is about, you cas't just expect offers for something people know absolutely nothing about. I've spent the last couple of years beta reading for other AWers, but I would certainly have never offered my services for something I knew nothing about.
Is the novel finished or in first draft?
What genre is it?
Etc, ect.
Oh, and you're more likely to get offers if you've shown your merit on these boards: Doing some critiques of your own for instance on SYW.
