Was just wondering is there a way to see pm that you sent ?
Not unless you specified to save a copy in your outbox on the bottom of the pm, just before you click send message.
You can set the option to be clicked by default...just go to profile>modify profile>Personal Message Options and make sure the "Save a copy of each Personal Message in my outbox by default." is checked.
To view the sent messages, go to the personal message page and look to the left and you will see a link to the outbox (sent messages)
