If you did not value your BTC talk forum accounts enough in order maintain them, then the existence of such account(s) (if so) would not necessarily contribute to your current supposed increased status that you are attempting to assert with your current account. 

Accordingly, if you have meaningful forum experiences, then perhaps you will be able to share those forum experiences and continue to make contributions to the forum, and sooner or later your experiences could be able to shine through your contributions, perhaps?  that is if you don't get too caught up in trying to assert largely irrelevant status claims that no one can really verify (and it does not matter too much) anyhow.

By the way, if you are merely attempting to assert status without having access to the prior accounts, then that seems merely a sign that you are relying on the wrong types of factors in order to get other posters to appreciate your past contributions, assuming they exist.
