Forgive my nosiness, but am I mistaken in assuming most jellies who answer me above 10,000 lurve aren't computer geeks?

Have a look at the orphans questions and you will find that a great part of them are computer/technology related.
There is, as far as I know, only one person here that is able to answer computer related questions.

I think there are a few here but not many.

We have at least one physician, one CPA, one lawyer, one computer whiz, and a few people who are strong in science. Questions do seem to get answered.

I think you are correct.
