Sapphire W34P0N,
I have the answer about who's been here the longest:

ADMIN
There used to be user records, but much was lost in several major events, the hacking event probably being the worst one.
Even with all of the user records, many people have been on and off of the forum with different user names after the major events. I could be wrong, but I think that Sincereheart and Symphony have consistently used the same name, even after major system events.
Love In Christ,
Tom
