I've never heard of something like this before, but I'm definitely interested in giving it a try. I just went out to their website at
http://www.keeper.com and looked at the order form. It asks for a "Friendship Code". Supple Cow - since you are the presenter of this concept to many of us in the forum, is there a code we can use so that you get credit for spreading the word? I didn't know if this "friendship code" was something that might get you free stuff or something - i couldn't find any info. I think if so, you should definitely get credit for enlightening all of us!
Thanks for a great post!
