It's entirely understandable that busy folk like mods disable incoming Conversations except to a restricted group they select. But please add a WARNING if I as user try to PC one of these members. At present you go to all the trouble of setting up and writing a message and then you get a notice saying the recipient doesn't accept PC --- but only AFTER you click Send. I just tried to send Floris a thank you for an unusually perceptive comment he put on my profile. None of Floris fault but the result was (on a primitive reaction level) that I felt rejected and annoyed when I was trying to do something nice. This could actually affec t a relationship with someone - not everyone can stand back and say it's the software! SUGGEST: As soon as I type the name of a user who blocks PC in the form, a message appears saying - "Sorry, NAME has opted to not receive private messages. You can still communicate with them in the ordinary forums."
