Is there a way to see your sent messages on here? It’s kind of difficult to keep track of every conversation without that feature.
If you go into Profile on the left it says Personal Message Options click that.
Now check mark “Save a copy of each Personal Message in my outbox by default”
That will keep the messages you sent out in there.
Alternatively, if you only want to hold on to specific messages, check the “Save a copy in my outbox” box when you send the message.
