Sounds like we're actually all on the same page about the grammar/punctuation/spelling thing! When you first mentioned not minding fixing people's grammar mistakes, I was envisioning the sort of submit that *is,* well, tangled and unreadable, whereas it sounds like you were envisioning a few typos, heh. I don't mind the occasional trip up either, especially when people are receptive to their critiquers (as you and eqb have said).
Agreed. I should have been clearer on my definition of acceptable levels.
Re-reading my post, it sounds like if it's even close to literate I have no issue with it.
