The transition to the new format gutted the participation by cutting members off if they didn't go thru the clunky renewal of id and password.
I still check it every few days but I used to check almost daily but there is just less of interest and I've mostly transitioned to facebook.
I'd suggest reaching out to the members who have dropped out with preset id/password that matches their old id/password and ease up on the security checks...this site doesn't contain a lot of critical private info that needs top of the line bank account type security.
