Where’s the summary of your own suggested edits?
I think it would be good to provide access to all one's edits, regardless of whether they are approved or not, as I (for one) don't spend time making arbitrary changes, only ones which I believe make something clearer, or more correct for myself and others.
Could adding edits that were done, but not approved, be added to a user's profile. This way, edits that one thinks are helpful would still (at least) be available to this person for future use / reference.
