Another proofreading request

Hey!

Would anybody be willing to proofread this:
www.beckerscarsten.de/conlang/ayeri/ayeri_course.pdf
<http://www.beckerscarsten.de/conlang/ayeri/ayeri_course.pdf> ?

I asked someone else already, but he told me he'd do it when
he feels like conlanging again, and that may take a
while. :-/ I want to publish this thingy finally! Actually,
it's just the exercises that would *really* need to be
tested. The grammar stuff should be OK so far.

Thanks,
Carsten.
