Why cant I send private messages? There not showing up as being sent.
They could be sent- you just may not be seeing a copy in your messages folder.
Go to your homepage/profile and click Edit Options (under the Quick Links tab near the top of the page) in the Control Panel list on the left hand side once you . If under "Private Messaging" the check box is unchecked for "Save a copy of sent messages in my Sent Items folder by default" then that will be the reason why. Check the box and you should start seeing your sent messages.
