The name is not new and was in used way before the JW's "trademarked" it.
Many of the older bibles will still have it, though most of the revisions hav either gone back to LORD or used the more correct versions of "Yahweh" or "Jahweh" or even "Jehweh".
Jehovah is a perfectly acceptable name to use as long as one is aware of the history behind it and why it is not correct in the "hebrew" sense of the word.
The thing is, it is NOT THE name of God ( no more than any of the other versions and perhaps even less) and it is NOT needed for anythin other than if one chooses to use THAT praticular designation.
Using Lord, Jah, Jahweh, Yahweh or any of the many other ways that it COULD be is perfectly fine since we do NOT know for sure.
What we DO KNOW is How Jesus commanded us to Pray and how HE prayed and , at least for me, that is more than good enough.
