It's in their "Mind and Soul" category, but you can find it directly with the above link.
My article explains how that feud started, and how events led to the 2010 reconciliation.
(Updated 2012-02-04): As I had hoped, this article is now "featured" on the Mind and Soul topic page in Suite 101, and also on their main page. Note that "now" is a temporary word, especially because writers submit great new articles frequently. Still, it's nice to get the recognition. See my writing tip, below!
As always, I also publicize my article in DeHaan Services ("Why the Lutherans and Mennonites Reconciled") and in my Xanga blog ("Reconciliation between Lutherans and Mennonites").
First, the Topic Editors at Suite 101 sometimes post requests for articles in their topics. Often this means that a good article has an above-average chance of being featured in that topic.
Second, I have contributed articles in this area.
Third, this happens to be an interesting topic: personalities clashed; life or death decisions were made.
So the writing tip is to track what your readers or editors want; know your own strengths; and deliver when the two mesh.
