I have downloaded enough things from Sourceforge to blow up a few computers (or at least hard drives). I just started this project on Sourceforge, but have been working on it since 1995, the year I got my degrees in biology and chemistry from Wayne State University and also started teaching ESOL. The only diagram I have uploaded was created using Dia which (for now) you can Google and download if you're interested. I need advice from any quarter and if you are interested in helping, great. The thing I need is financial help which, based on what I have up here at the moment, I don't merit. I could also use questions and comments should you be crazy enough to be interested enough to read this. I have to work in the morning, so I'm stopping now. To quote Mr. Rogers, I can stop if I want to.
