Hello Chris,

I finished (I believe) the mailroom assignment. Would you mind taking a look at it and let me know what you think?

Thanks a lot!

Michel.

PS: Thank you very much for the help with git & github today.
give this a shot with string formatting -- either the % operator or the format method. adding string is fine when it's this simple, but formatting is a lot more flexible and faster when things get a bit more complicated.
