My understanding is Lisa wanted to escape the attentions of a certain individual or individuals. So she wouldn't want anyone (except her trusted regulars) to know what nom de guerre she's currently using--because that would defeat the whole purpose of changing her name, wouldn't it?
So I wouldn't expect her to come back here and make a loud announcement. Much as I'd like to get in contact with her myself--since I never got the chance to try out her fabulous arse.
