I believe craigslist.com is a cheap immitation of the .org site..
Sometimes they grab multiple address' so someone can't do that. Looks like you can get to craigslist either through .com or .org, Netzero is the same way, you could email me either @netzero.com or @netzero.net. My clubs website can be accessed through spinnin4s.com or spinninfours.com, we own both and linked them together.
