For those KF users who are also LinkedIn users, I've created a KivaFriends.org group so you can proudly show your affiliation, if you'd like. Note: I'm more than happy to turn this group over to the moderators or Joe if it is inappropriate that I'm currently managing it. I'm an active LinkedIn user and have a Saab group there as well, so managing is a daily task for me as it is.
You can find the group by going to the Groups directory here:
http://www.linkedin.com/groupsDirectoryIn the Search Groups bar, type in Kiva and hit Search. Up will pop a number of Kiva groups and at the bottom of the list is the KivaFriends group. Click on the KivaFriends logo to request membership. Approvals will happen daily.
If you'd like to see what this whole thing looks like - it's just the KF icon on your LinkedIn profile, that's it - then you can view my public profile and see both my KF and Kiva group logos among others here:

p.s. There are a number of Kiva.org groups too, but I joined the one at the top of the list. I think that's the most official one.
p.p.s. Just to clarify, all that a LinkedIn group does is to put a little affiliation logo on your LinkedIn profile. There is no other functionality associated with it. It all links back to here.
