@S.Carnahan I have added a screenshot to your answer about logout. I hope that's ok - feel free to edit the post further if needed. (Although I think it goes without saying.)
@HarryGindi sorry to bother you. I've developed a bot which automatically repairs broken image links. I try to check manually if there are more things which can be improved. It's limited to 1 post per site on sites where I don't have edit privileges like MathOverflow; however, wiki posts are treated a bit differently. I'll try to tune down the edits a bit to be in line with your guidelines.
