I think we should have one day when the last MitM episode comes, that day should be like a big party in the MitMVC. Everyone shall have fun to take their minds off what's going to happen.
I think a card is a very good idea though because it's easy to do and it sends a great message to everyone that it concerns, maybe they'll even write back.
We could write a long letter, that's another idea!!
I will think of more ideas soon, i promise!!
