I just noticed something when trying to direct someone to a specific page at Scratch ed, in the regular Scratch forums. The pages all have the same URL? Being able to give a particular resource's address is handy, or is there another way to link to a specific section of this site?
Got it and that fixed the problem.
I notice that you're using scratch-ed.com as the primary address. Try using scratched.gse.harvard.edu-- and the address hiding problem should be avoided.
Let me know how it goes!
