Stupid question from someone who should know better...

Like the title states, this is a really dumb question that should be answered quickly.

I've beaten the game with 2 different teams and I want to get onto the Side Quests and the Iron Giant, but I'm not exactally sure how to open the side quests.

Do I just keep sending letters to the designated NPC? Or do I have to spam other People over Wi-Fi? And furthermore, is sending letters the only thing that you can do over Wi-Fi?

I actually think there is no point in sending mail to NPC's other than to waste your time...
