For those of us that spend some time in jail we tend to browse the forum and stumble upon some decent posts. I've noticed that there is a tip button but when you try to tip it says undefined. 

How about being able to tip jail posts when you're in jail but with a twist. You only pay them after you get released. When you're inside you don't have money or access to anything from the outside world. In this case it's more of a promise. Like you see in  the movies/TV shows guys who get released sometimes remember their old jail buddies and help them out. You tip a post as soon as you get released either the money that you have on hand or in your bank account gets sent to them.
