Hi Joe!

I've been so busy bouncing between So. California and the San Francisco / Oakland / San Jose areas with CCTV Installs and surveys, it leaves me with almost no time to even see my Wife!!!
Due to this (and more precise, the Head of the Electrical Division is too dificult to work with) I am considering other Employment options ASAP!

Keep me informed to the Electric West show, so I can visit you there.

I'll check out the NTT site too.

Scott S.E.T.

added six (6) new items to the Technical Reference area.

Look for links under:
"* New As Of October 18th, 2002"

Also created discussion threads in user accessible areas, such as the "Electrical Theory And Applications" area and the "General Discussion" area.
