And concernig the amount of request to what features should be implemented. Where did you get this information. Amount of track tickets, forum posts, mailing list? I'm new to the RC project and interested in voting on the right place ;-)
Thats just from our own company. We offer roundcube as a webmail client, and we get regular requests for contact groups allowing you to send email to a list of people instead of having to add everyone separately. I have yet to see a request for PGP integration, and we dont offer it in squirrelmail either. I think the average joe doesnt use encryption. Although you could argue that if it was more accessible, they perhaps would ;)
