Picky, Pickier, Pickest--What's a Pickest?

This is a site 'for teacher's and students of English'. Non native English speakers might find it well worth examining (and some native ones as well!)

I can't help it. I drive everybody I know nuts with my obsession to cure the world of grammatical errors:
"teacher's" is possessive when I think just a plain 'ol plural--"teachers"--should do.
Anybody know of a 12 step group for obsessive correctors?

Hey, shouldn't that be "12-step group." What keeps me in line is the thought that if I correct someone's grammar, R. Berg will correct my correction.

Yes, the hyphen belongs there. But you left out a question mark, didn't you.

The "English Rules" site doesn't say "for teacher's and students." It says "for teachers and students."

I see I am not alone.
And should the subject line read "Pickest" or "Pickiest"?

I meant to do that.

I hereby declare an amnesty for the rest of this day. Or at least the re'st of thi's thread.
