I wish Nintendo had planned this better. In order to unlock the bonus dungeon, and a bunch of other extra stuff you need to send letters to NPC's through mognet. Good enough for me, but you can't send more than one letter to each npc unless you have sent a certain number of letters to friends over mognet first.
Crap. Well, what if i don't have a friend in the area who has a DS and FF3? They should have made a feature where you can go onto WFC and look for pple looking for friends to exchange mail with instead of making us already have someone else's friend code to input. I have the same beef with Mario Kart DS and Animal Crossing Wild World. But, that's the way the system is set up currently, so instead of complaining more (i just really needed to get it off my chest and see if anyone else agrees), Here's my friend code for Final Fantasy III in case anyone wants to exchange mail. Remember to post yours so I can add your code to my adress book so i can get it.
