I know that Richard & Smut Gremlins use the same admin script as me & that error you're getting means that your site is currently listed (once a site is removed, it goes into a different database file that the submit pages doesn't look at) So resubmitting it would be a waste, seeing as it's already listed
Like DDave said - I'm 6 months -
