So I am Thinking of Starting a Group, Input Please!!

So the past few days I have been thinking of starting a group challenge on MFP. I have not ironed out all of the details yet, but because many of the challenges are focused on weight loss, I was thinking of focusing on two other aspects of weight loss and not just the physical but the mental and physical as I believe they are very important to my well-being and everyone elses too. Each week I would give a suggested spiritual reading, and a fun mental activity such as doing a cross word puzzle or meditation exercise. Again, I don't have all of the details figured out but those are the ideas that I have. So I would like to know if anyone would be interested in such a group and if so, what are some suggestions that you have?
