I don't know if this is possible for you do to Mr.Yoshi P, but my friendslist is full and I need more than 200 spots.:(
Another thing is with 200 friends its very hard to find the person you want to send a letter to using the moogle mail system, it would be easier if you could put in the first letter of their name and it would find people with that letter on the list or something.
Thank you, I love you, Bye!~
