When I was in the Mennonite Church we practiced footwashing alongside communion (well we washed feet first~men and women were separated for this~then did communion) and found it to be an enriching experience. They use scriptures for the ordinance, but it is not a required practice.
Also they practiced the "Holy Kiss". Yeah, I sorta passed on that one myself opting instead for the "Holy Hug" :cool Seeing two old Mennonite farmers kiss each other on the lips was kinda odd for me the first time I saw it. The older generation would pair off with each other and we younger generation would pair off for this during the feetwashing. The old timers would kiss when they greeted each other on Sunday mornings.
Now in the Old Order Mennonites I guess they're still a kissin'.
Hey, Paul said greet each other with a holy kiss, so they take it literally.
