Carol, I'm not sure how much this is really a problem. But I have been told to do this by several computer geeks:
Just to avoid spam, you really shouldn't put your email address in a public forum.
If you do, one thing that will help avoid automated trollers (which is how most spam is sent) is to use the word at instead of the @ sign.
Most people will realize the correct way to use it, but most automated systems will not catch that it is an email address and won't pick it up.
Sometimes I have to remind myself, everything we write on these boards is actually open to whoever in the entire world is interested in reading them. I have googled my name, and had several of my comments here on the boards have come up in the search.
