You've always had a hunch that you're funnier than Letterman, smarter than Oprah or a better cook than Emeril. Well, here's your chance to prove it, big talker: Whether you're a Wayne-and-Garth wannabe or an aspiring talking head, most local counties have at least one nonprofit public-access channel dedicated to programs produced by community members.

Staffers at local channels are usually happy to assist you in translating a germ of an idea into a full-blown show. They can help you learn skills to pull it together, as well as hook you up with volunteers to round out your crew. If you're willing to spend the cash, most also offer professional production services for hire.

Paul LeValley, executive director of Arlington Independent Media, says realistic expectations are the secret to making great TV. "Recording the history of the world may be a good idea, but it's not doable," he says. "Start out with shorter programs that feature local people and places." Budgets and time commitments depend on how elaborate you want to get.

Cable access has launched careers -- Michael Essany, host of his eponymous talk show on E!, started out drawing stars such as Kevin Bacon and Jewel to his local Valparaiso, Ind., show. It can also provide a few perks of minor celebrity-dom. Springfield resident Larz LaComa, whose long-running "Larz From Mars" features a wacky mix of local artists, musicians and businesses, says cable access has allowed him to spotlight otherwise obscure talents. "It's so rewarding to have the chance to put people on TV who wouldn't otherwise get that chance," says LaComa, whose show debuted on Comcast's Channel 69 from Arlington 18 years ago. The occasional fan recognizing him on the street doesn't hurt, either, he says.
