In my case here are my member IDs:
Omnimaga - 1 (well, duh)
United-TI - 176
MaxCoderz - 40 (although they had multiple board resets. I signed up in August 2003 on the previous one, but it used cryptic member IDs. For example mine was 75-1063909752)
Cemetech - 15
Cemetech's previous board - 17
Ticalc - 45556
But of course I was not very active early on on Cemetech and on UTI I was barely active during the last 3 years.
