Would the REAL NAME please come forth?

This subject flies around the internet as fast as fingers can type! Is it God -or one of the many variations...and these are just some! YHVH YHWH Yahweh Yahveh Yaveh Yaweh Jehova Jehovah Jahova Jahovah Yahova Yahovah Yahowah Jahowa Jahowah Yahavah Jahavah Yahowe Yahoweh Jahaveh Jahaweh Yahaveh Yahaweh Jahuweh Yahuweh Jahuwah Yahuwah Yahuah Yah Jah Yahu Yahoo Yaohu Jahu Yahvah Jahvah Jahve Jahveh Yahve Yahwe Yauhu Yawhu Iahu Iahou Iahoo Iahueh - OH MY!

There are many websites and info sheets and authorities and not-so-good authorities that claim they have the answer - well, if all these experts know what it is ... why is it there are so  many variations? Surely He would not want us to miss out on this most important blessing of being able to call upon His name!
