First, make sure you're logged into the forums here.
Then go to the main ask the therapist page and click on the link on the left-hand side where it says "Ask a Question." Let me know if that works.

If not, the problem is with the particular type of Web browser you're using, or a toolbar you've installed that is hiding referer information from our server. Try a difference Web browser (like the free Mozilla Firefox
http://www.mozilla.com/en-US/firefox/ ) and see if that helps.
