It appears that the edit history always shows the post starter as the member who edited the current version in the history. For example (see screenshot): 1. testuser starts a post. 2. testuser makes first edit. 3. alex (= moderator) makes second edit. The way the edit history depicts the information (with the selected radios for old and new), you'd think that testuser is the one who last edited ("current version") the post. Perhaps I am just misinterpreting the meaning of current version?
