Bwah-ha-ha! No, your grammar is pretty good, as far as I can tell - I've sprinkled on a few more commas, because I'm like that (but the rules on commas are pretty vague, as it is). And *smacks self* I will send it back to you today.

Quite frankly, I can't remember what half these things mean anyhow. Apposi-what? ;)
