I went to edit my question, and got put into a revision editing list somehow, and I see that someone has edited it since I started, but there's no link back that I can find. Would it be possible to add one?
Bit of a pita, I agree. Pasting the URL back minus "edit" produces "Page not found". Leverage the tabbed browsing feature that your browser supports. Edit in another tab so you've always got a source tab to get back to the question.
It's a problem in general, the envelope is another example. Jeff & co work on "check what's going on" once a day, maybe a couple of times a day. Not quite compatible with the 9 minutes that a question can survive on the front page. We might not have done a great job explaining how we use the site.
