An "expert" or genius" are words thrown around these days. They bring to mind people who are rigid, "know it alls" who thinks they always are correct and can not learn from others. They cross every T and dot every i and do things by the book. PR on the otherhand, teaches people to have a 'Beginners mind", have fun and play, not to be so rigid. And, PRers DO learn from others: on the forum and other ways. If I had to name four people who knew the system (currently who uses the forum) they would be

Alex K
Young Prer
Iam2
Michael Saikali

They know the system, but they do not clam "genius" just people who want to find and use a more efficient way to enjoy life and learn something in the process.
