Yes, that's grammar. People who write grammer are illiterate sub-humans, or just in a hurry.
Anyway, I proof-read and edit in the real world.
I love wikis, because I can correct everyone else's grammar and spelling without getting punched in the stomach for being a snotty-nosed little know-it-all.
I still am a snotty-nosed little know-it-all, however.
If you have a page that needs an editor's eye, I'm available.
Until I have some proper stuff to stick here, I've lazily slapped on a bunch of user templates. W00t.
