Hi! We were wondering how far in advance Idea Pins should be submitted in order to be considered for being featured on/by Pinterest, when we submit them for monthly trends features? Since they are topical and timely, how far in advance does Pinterest need them in order to review and then decide? Is there a general guidelne for this? For example, if we want to submit an Idea Pin featuring a Romantic Valentine's Day Menu for consideration to be featured by Pinterest, when should it be submitted?
