This plug in is definitely easy to use, but there is one huge problem. If you share a draft with anyone, definitely make sure you don't go back in and make any changes to that draft. If you do, the original link you shared becomes inactive. I see this as a major flaw to this plugin. I use a similiar feature on a wordpress.com website that I work on, and I can change the draft as often as I wish after I've sent someone a copy of the link.
