This opaqueness drives me nuts, isn't that the inverse of community? Why don't people just use their real names? I guess it's because they have something to hide, like flipping machines! I've been D-Type for over 20 years on video and pinball related forums, so I put my name in my signature, in a not-obvious form for search engines.
I knew loads of people personally from the Yahoo groups forum, many of which probably migrated over here, but I don't know them by handle on the forum so it's like starting all over again.
Nick Bennett from Pinsanon had a website called pinballfaces that was a directory of all the community members, that was a great idea, I reckon.
