Same here....came on as oxydolfan, forgot my password, reinvented myself as oxydolfan1....
I don't post on vacuumland but do read the posts occasionally...one new procedure they've developed as a result of problems is that you have to submit your full name, the webmaster checks it off and then you can post....I think that would be a good idea, to avoid members posting under more than one handle...I'd also feel more comfortable with at least that added level of security.
In addition, I believe that underage members (18 and under) should be somehow indicated....sometimes, discussions tend to be, well, shall we say, inappropriate for underaged members, and we should know what the participant's status is.
