Do you know how old the account is? RYL moved to V3 in 2007, so the post history prior to that is gone. If your account was here after 2007 you should hopefully be able to use search to find the profile & posts.
RYL doesn't have a live chat at the moment - there's a post explaining it here https://www.recoveryourlife.com/foru...d.php?t=255304
There is the Veterans Corner, though it's not really 21+ so much as it was for the older members at the time, but nowadays the majority of people here are adults anyway.
