Please, stop trying to type the absolute bare minimum, or we will be here all day!
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with. And the better the information you give us, the better help we can give you.

So what does this app do with the info?
What should the service do with it?
What problems are you having in converting it?
What help do you need?
