When I have registered

[bmo]

1. I have not registered yet, when I do, I will let my friend now. Do I say:

(1) When I have registered, I will let you know.
(2) When I register, I will let you know.

2. When asking someone if he has his lunch,

(1) Did you have your lunch yet?
(2) Have you had your lunch yet?
(3) Did you have your lunch?
(4) Have you had your lunch?

Which is correct?

Thanks. BMO

Yes, definitely!

2. When asking someone if he has his lunch,

(1) Did you have your lunch yet?
(2) Have you had your lunch yet?
(3) Did you have your lunch?
(4) Have you had your lunch?

Which is correct?

Personally I would say that none of the examples you gave were "natural sounding". I would say "Have you had lunch?" or "Have you had lunch yet?".

Red's sounds more natural to me, but 'your lunch' also works for me. ;-0

Thank you both. And the first one, are both of these, when I register and when I have registered, correct? Is one preferable over the other? BMO

In the first, either would be correct and have approximately the same meaning.
I have heard all of the variations in #2. It is a bit colloquial with "your" in there.
