Bread-Bakers v102.n025.4

Can anyone give me some help constructing a nice high loaf of Millet/Rice 
bread?  I tried some at a health food store and it is pretty good - with 
great crumb.

Here is the list of ingredients:  Millet flour, rice flour, sea salt, 
baking powder and water.  I tried it and not much success.  Any ideas?
