How do you send e-mail addresses and/or other info to “askers” without broadcasting it to others?

Costa Rica ’03: How do you send e-mail addresses and/or other info to “askers” without broadcasting it to others?
More than several times in “Answers.Yahoo” I have seen answers where individuals ask to be sent an e-mail address or ask to be invited to some activity or location. Is there some way of sharing info with an “asker” or “answerer” without “broadcasting” it to all other viewers? Or are these individuals willing to do that and “don’t care?”

If you click on their avatar, some folks have their email, 360 or IM links open for contact. For the email, it is a ‘blind’ link — the email is passed via Yahoo Answers and you don’t get to know the other persons actual email address. That is pretty safe.

Others actually give out their info on the site, but that is against the Community Guidelines.

You don’t send or broadcast email address. There is no way to do that in a public forum, and people shouldn’t. If those requesting information allow emails upon checking their profiles, it can be done that way.
