I am not a native English speaker. I have never been to an English-speaking country. My English is very far from the ideal. Often I make errors, and see them only later. Often I can't find a good phrase construction while writing and change it later. I am rereading my posts many times for it. Of course, once or twice somebody comes and repairs my language, too. For me, and I think many other non-English speakers, or English perfectionists, that ceiling of 10 edits is impossible.
A good writer can change his or her text many times. Why should such posts go to wiki? Why should these posts give no points into reputation?
Please, could you make a check field "language editing" on the edit page (unchecked by default)? If checked, it wouldn't be count into these 10 changes for wiki.
Tim Stone's idea, to remove this automatic rule at all, is even more likeable for me. I only wanted to propose the minimal changes.
