It's OK to call me friend I consider it an honor. : )
About God's name, true, the exactly pronunciation was lost due to the beliefs that developed later. Some say that Yahweh or Yahveh are the closest to the original. Others use Jehovah. In that way they strive to heed the constant commands that God's name be glorified and made known. It has to be kept in mind that the name "Jesus" is pronounced differently in every language. Yet if you call upon him he knows it is him who you are calling upon. So in a sense it's the effort to heed the instructions that is commendable. It is also commendable that the Jews strive not to misuse God's name. But of the two efforts I feel that the one which strives to heed the commands of making it known is to be preferred.
But please let me clarify something very important. I do not feel that mere pronunciation of God's name or avoiding using it in vain is enough to make a person righteous in God's eyes. Above all things God looks at a person's heart and judges accordingly.
1 Chronicles 28:9
"....for the LORD searches every heart and understands every motive behind the thoughts...." NIV
Also, God promises to make such knowledge available to everyone on earth.
Habakkuk 2:14
For the earth will be filled with the knowledge of the glory of the LORD, as the waters cover the sea.
NIV
So our lack of knowledge in this area is just temporary. : )
