Wikipedia Edit: Rent

I just fixed some of Act 2 on the Rent Page, there was some clarification needed about the fight between Mark and Roger. I am a little concerned because the last edit that I made to the Rent page a few weeks ago, does not show up in the history of the page. The only thing I can think that happened was that I wasn't logged in at the time I edited the page, but there wasn't even an edit in the history on the day that I thought I did it. It bothers me because I almost completely rewrote Act 1 and it took me a long time to do! Is there any way to check that?
