Harry Potter RPG in a letter

Recently I hosted a swap in my group Harry Potter Freaks (awsome group for Potter fans by the way) in which you had to write a letter (as a character of choice) to another character of choice, and what that character would write back. I'll do that again sometime. But for now I wanted to extend it some more.

You send a letter to your partner as a character of the series (which you will post below.) check there first each character can only be taken once, to avoid having to send a letter to "yourself". Of course your partner will have picked a character as well, so you will (as your character) send a letter to your partner's character of choice. This letter should be at least an A4 page long, can be typed or handwritten.

so let's say I pick Snape and my partner picked Voldemort. Then I will write a letter to Voldemort as snape.

Your partner will reply to that letter ans then you write one back and then the other, and so on and so on. For as long as you like. You should remain the same character of course you cannot receive a letter for Dumbledore and write back as harry

as for ratings: a minimum of 4,5 and no 1' or unexplained 3's

You can include a little extra like a sticker sheet or something (or a bigger extra if you like) it's up to you. You don't NEED to send an extra though

I hope you understood that a bit.
