Which other forum?
When did it go blank, when you "Previewed" your post or when you hit the "Submit" button?
Were there any error messages? Usually a person who has not signed up for the CNET forums will be taken to a generic "Sign up for instant access to the forums" registration page if they click a Reply button on any post;
If any non member clicks one of the "Create a new thread" buttons, they are taken to the same page.
You mention you have had to rejoin. What was your other signup name?
