Is there some way to send private messages to other members? (ones that don't have emails listed) If not, this would be a nice functionality to have, wink wink ;)
this was suggested before by several members but it is still not available.
I would suggest that you can use shared feature to substitute private messages.
you can then have shared space with any member or group of members and you don't need their emails.
When you're not logged in and looking at someone profil, there is a contact button instead of the follow button. When you click on it, there is a field for your e-mail and an other for your message then send. But it seem it does not work, since someone tried to contact me that way and i recieved no notification.
