Although that would be great if it was allowed Janet, I'd be careful advertising this or any site on a different site. Some get really nasty about it... especially if they're paid for by sponsers who fork out advertising dollars for the privilege. I've worked at 3 different sites that were sponsored and none of them would allow that. More than likely you'd get a warning about it and the post would be removed.
Some will go so far as to pull your posting privileges for it.
