I work for San Diego State University in Business Information Systems. My previous position was with Computer Sciences Corp (CSC), as a Consultant/Programmer/analyst.
I have been using TCL/TK for personal use since 1995, heavily the last 6 or seven years. I was interested in developing editors and tools for software development for my own use.
I may occasionally be seen listening in the chat area as AEC.
I'll post more here as time permits.
