Here's my comment I entered on the Glutino/Gluten Free Pantry website:
"Many of us miss the Angel Food Cake mix terribly.
Here's a blog I posted about it, that includes links to many other people's comments about how they want it back:
Your mixes are among the best. We all love them. This was a wonderful product. I can't understand why you would take it away. Please consider bringing it back. Nothing else compares to it.
I'll let you know how they respond, if they respond. Here's the link to the comment form, where you can leave your comment/suggestion to them as well: http://www.glutino.com/content/view/54/63/
