Things you need to know about the new ‘Conversations’ PM system:Dismiss Notice
a) DO NOT REPLY TO THE NOTIFICATION EMAIL! I get them, not the intended recipient. I get a lot of them and I do not want them! It is just a notification, log into the site and reply from there.
b) To delete old conversations use the ‘Leave conversation’ option. This is just delete by another name.
