Hello (again) Tammie lol
Something very minor but I just realized it now. In the front log-in area you are missing a "Lost your password?" link.
Nothing big, I just wanted to let you know in case you wanted to throw it on there in a future upgrade.
Also, where is the "Lost your password?" page located in the file structure of WPMU because I would like to change the wordpress logo on that page the same as the sign-in page.
