FYI If you miss selecting a topic or providing a specific subject, your "Ask a Question" box will kick out an error telling you what you've missed. Even after correcting the error, and clicking "submit" again, the form does not detect that the error has been corrected. The only way then to submit a question is to copy what you've written, reload the page, and fill everything in again.
It's not terribly difficult to work around, but it is somewhat annoying. Just something you may want to look into fixing.
