Re: Yahoo Connect?
One answer re popularity of Yahoo! email addresses would be that Yahoo email addresses were required to set up free websites in their now defunct Yahoo! Geocity sites (RIP Oct. 2009) and millions of free Yahoo!Groups users and members. There are groups set up in the 90’s which are still active today.
Yahoo!Groups * Members Only * Messages * Post * Files * Photos * Links * Database * Polls
* Calendar * Promote * Groups Labs (Beta) … including email notifications from group which members can reply to from email.
