This isn't a simple-substitution code. You're on your own.
Just a heads-up, because you're new: We have to deal with folks rather frequently who try to get us to solve problems and homework for them. We don't really like that. If you want to talk about cryptograms and random thoughts that cross your mind, we're generally friendly people.
Hope you get into the crypto-craze.
