Oh yeah - you can also get involved with "trees" or "vines" on sites like Trader's Den (and many others). All you need is a mailing address, a DVD burner and your good. No need to worry about having something to trade. You sign up for for the vine, wait your turn and it will be mailed to you (for free) to copy - then you mail (you pay postage) the copy that arrived at your door to the next person on the list. Of course, this is only for live shows, no studio releases.
