Hey! I would love to do a log with you and that sounds super cute! Successful patronus casting is something that gets rolled by the mods, so you'll probably want to hit their dropbox and ask for Patronus permission or a patronus roll, and mention that he practiced with Lucas and that'll give you a bonus to the roll (Lucas is Charms TA so anyone who asked him for help got a small bonus to their roll). Once we know how your roll goes we'll know how to handle the log. :]

As for the log itself, I am out of town until Monday, but I can write a starter in a gdoc maybe Sunday evening and mail it to you, if you want? :)
