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.
