Thanks for the invite, sounds interesting. Perhaps if/when your
meeting is in the Portland area, I'll check it out. Thanks again for
the help, really appreciate it.

but like what the road to you-know-where is paved with, that's only
sometimes). Next meeting is this Saturday, south of Seattle near
Auburn. Lots of different levels of experience so don't be bashful.
Besides, it's fun to see what others are doing with AB, the markets,
computers, etc.
