### WORK IN PROGRESS

This site is still under
reorganization.

Links are being reconfigured and some are inactive or
incorrect.

Older pages need reworking to be made handicapped
accessible.

Links starting with "www.humboldt.edu/~mef2" are being
readdressed as needed with "users.humboldt.edu/flashman"

I continue to work on this.

Flash :)
