I don't think it's a rule, as such. Chutz (one of our moderators) would know more. I think it has something to do with computer programs being able to pick up an e-mail address from our posts and use it (or misuse it), not that the people on the forum are going to misuse it.
If you click on Chutz's name, you can e-mail her. I wasn't meaning you were breaking a rule, as I don't think you're selling anything. It's just often recommended we don't put our e-mail addresses directly in posts so spammers can't pick the up. As I said, I'm not a techie! If you have your e-mail in your profile, people could click on the envelope icon in your posts and e-mail you and ask for his contact info.
I didn't mean to offend you at all. I think you're providing some great info!
