Your Private Messages? Towards the top right of your screen you should see 'Welcome Bpcyclist'. Under that there should be a link that says either 'Private Messages' or 'New Notification' depending on whether or not you have messages or notifications waiting.

Click on that link and navigate to your PMs. From there you will see your Inbox. While viewing, there is a control panel with links on the left of your screen. You have options to send PMs, search, track, etc. Also, there is a tiny down arrow next to the words Private Messages in the control panel. That lets you toggle between your inbox and your sent messages.

Hope that helps. Enjoy!
