"What did you think of my offer?" should be fine
As should be "What did you think of my suggestion?"
I agree "What did you think of my suggestion" is a better phrase.
Agreed. "... of my suggestion" is much more natural English than "... about my suggestion".
This is still not working in June 2018
Better English than their answer
It's December 2018, almost New Year's. What do you think of my suggestion flows naturally and is perfectly good English. The Hebrew translation should be broadened.
And it's March 2019 and "of my suggestion" still isn't there
I agree, kidsil. I wrote the same thing.
get your ❤❤❤❤ together guys !!!!!
Agree with others here completely. Still not accepting 'of my suggestion' in September 2018.
