***
Mark as repeat
Save the address of idea which has already been proposed
***
Grammar-wise it's not correct. The correct wording would be:
***
Mark as reiteration
Save the address of the idea that has already been proposed.
***
Yet, the meaning of the phrase: "Save the address of idea which has already been proposed" is not clear. What does it mean?
I tried to find it out by clicking on the link "Check the location", but it produces a blank page. Quite a mess!
