I really have needed a tool like this to turn a number of internal business documents into fillable forms. Do not want to have to buy a typewriter to do the tasks PDF filler can do so easily. Without any training I have been able to do the basic functions just fine. I would be interested in furthering my skills be learning how to do more sophisticated editing or creation.
