Since you seem confused about what option you had changed in your settings here on the forum that resulted in your not being able to send PMs to people not on your contacts list, we edited your options for you to fix this issue. It's probably a good idea to not change your options in the future without making a note of it somewhere what you've changed, so you can go back and change it back if it's causing you problems in the future.

I've attached a screenshot so you can see where this option was. We've unchecked the box for you, so you should now be all set.
