I have accepted all of the edit he has made to improve AskubuntuAsk Ubuntu. This can change when an edit appears that is wrong, but for now, he has contributed a lot to enhancing the way we read many Q/A. For the small edits like an uppercase letter I simply reject them. For example, when the case involved just changing 1 letter. Of course if he changes 1 letter and adds some tags that correspond to the question then I tend to accept.
At the end, he is simply improving the site, although minor edits should not be done, specially little ones (1 letter).
