The only signature area for myself and landlord is on the security deposit agreement, which my landlord said she would sign by March 10, 2006; a week after I received my copy of the full lease; including this signature page. As far as I know, she has not signed the original, or if she has, I never got a copy of it with their signature on it. Am I still bound by this lease even if the manager doesn't sign it? Or is just putting the complex name on the front page as landlord the same as if she signed it herself? Please help before I get evicted for them breaking their part of the lease and laws!

Probably yes... but not an issue. Even if this came into question - and could not be resolved, the occupancy would be deemed a "verbal month to month occupancy" - and even then, the landlord would have a right to have you move... if not by an eviction, by a notice of non renewal.

As much as you've posted about the hassles with this landlord, I'd strongly suggest just moving out... and the next time, be sure it's done right: Read every word of the lease, both you and the landlord sign it, and get a copy before you leave the office.
