Hello from Gregg C Levine normally with Jedi Knight Computers Thanks Paul. Even though he and I have only occasionally exchanged e-mail I am including myself in that rare collection of friends via the Internet. I figured that one of you were the lucky ones, who did use the E-11 product. Your name wasn't in the running, though, just a candidate. Oh and the list of candidates was a short one, maybe two or three. I'll figure out an appropriate arrangement for myself, and see what I can dummy up here. Can you post a recipe behind how you did your testing? And thank you for your quick reply. Gregg C Levine dr...@wo...
