Anything Goes : Protection from Sharks and Snakes by Matt Alexander Clark

Hi, As someone who is new to the film industry here in the UK I wonder if anyone who would consider themselves experienced, seasoned pro's has any advice on spotting fraudsters, charlatans, and those who generally would aim to rip you off; be it your ideas, or asking for finance, and so forth. Any additional titbits of advice that would help a newbie like me to get going and progress in the business are welcome too! Thanks, Matt
