Sites that depend on two-way email communication, rather than those that post questions openly on the site, or have real-time or message board methods. Please consider carefully what information you give to sites you do not know and trust. See also Members Only, which goes a step further and requires registration.

This category is for sites that respond to readers'' requests for advice, whatever the topic, by e-mail.

Please read the category description and look at the sites already listed. Also, you might like to browse other categories - one of them might be more appropriate.
