How do I make brown rice bread rise without any wheat flour?
I have been making a gluten free yogurt bread with the brown rice flour and haven't had any problems.  You are going to need xanthan gum with any kind of gluten free mix you need.  

With the other gluten free bread recipes I have in my book, they are all calling for a tsp of vinegar in addition to the dry yeast.  Not sure if that helps with the rising, but my recipes have all come out exactly like the book says and haven't had a problem with them not rising.  I just turn my stand mixer on HIGH and don't worry about kneading the bread.
