Things ya shouldn't lend:

You can't lend PC Games and Music on CD's. I'm still looking into whether or not you can lend CD's for free... like libraries do. Call your congressman and bother them about it. Tell em you got a stack of CD's you paid too much for and you want to lend them out for a buck a week.

Don't lend out irreplaceable things... priceless things, and things that you use every day. But that's just common sense.

Don't lend Weapons.

No adult content on this site... sorry. I'm sure there'll be a site available in the future for that ;)

When lending vehicles, make sure that your insurance covers any driver, and that the borrower has the appropriate credentials.

Good Luck!
