Cool!!!! Hope you have informed the family, they had better get ready for all of those wonderful prints..
Don't worry to much about everything, just enjoy it. Before you know it you will be using Rodinal, Pyrocat-HD, Pyro, PC-Tea or some other developer...finding a 1:100 dilution that takes 30 min. or more and you will be thinking about that frist roll - only 4 minutes.
