Everybody probably already knows this
but in case someone doesn't:
If you want to know if someone is a member, here at PTS (and you know their screen-name);
- I click on "My Messages"
- Then I click on "Send a message"
- Under "New Message" I type in the screen-name in the "To" field.
If the person is a member here, their name will show up below the box and you can click on it if you want to send them a PM.
