As with most venues provided to the public at no direct charge, RF Cafe relies on the generosity of
independent advertisers to underwrite the production costs of the endeavor. It is with the greatest
sincerity that I thank the companies who have chosen to support RF Cafe.
Of course, without visitors (you), both regularly returning and new arrivals, there would be no incentive
for companies to spend their hard-earned money on advertising. My job is to see to it that advertisers
and visitors always have a reason to maintain a presence on the website.
