1. Select the envelope in the top right corner of the page (it will be next to your avatar).
2. Once on the 'Private Messages' page, select 'New Message'.
3. In the 'Send To' field, type in the name of the user you would like to send a private message to. Once you start typing a name, suggestions will auto populate.
4. Once you compose your message, select 'Send Message' at the bottom of the page.
As I said this has already been done and no joy here so no tech no P.M. Nothing wrong on my end at the very least it's bad tuning on installers end!
