If I request a mesage board request that my account be deleted what legal right do i have to force the owner to delete my account?

None the owner of the site is not required to delete your account. The only exception would be if it was a membership you were paying for.

I would suggest you contact an attorney to determine what legal options you have regarding deleting an account you have created on a message board. Your options may depend on a variety of matters such as the reason for requesting the account be cancelled. Some message boards may even allow you to edit your responses, perhaps even deleting them youself. Any additional information you could provide may help you get better responses.
