(general statement) - Wow, the messaging system is really... archaic.
(specific glitch)
The problem:
1) I search for a player and find them. I see the screen with the player name and clickable links below their name:
"Posts"
"Discussions"
"Private Discussions'
"Mentions"
2) I click on "Private Discussions" and try to start a "New Private Discussion". The "add recipients to your discussion" window comes up.
3) when I typed in the first three letters (or even the entire username) no selectable list comes up for me to chose the recipient.
4) Therefore, I can't address a private discussion to anyone.
This appears to be a software problem - unless there is another reason that I cannot message these players - they are not on my "friends" list - could that be the limitation?
