In Beta2 dexplorer, you’ll notice in an Ask a Question button on the standard toolbar.  Clicking this button takes you to a page that searches the MSDN Forums

You can also use the “Check Question Status” button located next to the Ask a Question button to check the status of your MSDN Forum questions.

And the last button in the group "Send Feedback" takes you to the Product Feedback Center.

Happy Visual Studio’ing!
