SEO

ok another question..i have two urls to my forum they are
www.rapfeinds.com and www.micfiends.com
but since i registered here with www.micfiends.com,www.rapfeinds.com is was added to my whitelist by me but it's still showing this when i try to login i using rapfeinds.com, 'In order to accept POST request originating from this domain, the admin must add this domain to the whitelist."

It seems to be a problem with your vB-settings.
Add the second domain to the 'Post Referrer Whitelist' in the common-category.
