Oh, I see. May I understand it this way:

Looking forward to hearing from you.

Thank you in advance.

Dear cumudgeon,

Sorry I didn't see this one when I posted the previous one. According to this post both 'where' and 'wherein' are correct. Is that right?

Dear curmudgeon,

That means 'In the clearing they made camp'. Is that right?

They are both correct, but the first is more compact.
