Ok... this is my entry =)

I Welcome some feedback @therealwolf

Forgive me the standards and code "beauty" as I am not a dev guy and besides some advanced troubleshooting skills, I can only try to learn from many in terms of programming skills. Either way... this is my contribution.

By the way... @steemchiller, you might want to look at this... as delegating with your tool, under some of these situations, will throw some "warnings" that I have "potentially" covered with this code. =)
