How to start a yeast bank.

[Orangevango]

Ive been looking into starting a bank of yeasts that I like, Ive got the freezer on top of my keggerator that can be devoted to yeasts, but I'm overwhelmed by the variety of advice given across the Internet, should I be working with agar slants, or with ball jars full of slurry, should I freeze or just refrigerate, can dry yeasts be washed and saved, how can I wash yeasts, is there a way you can tell if you have infected one of your strains? The list of questions is endless. I would love for some of the more experienced yeast-wranglers to put together a comprehensive guide to setting up a yeast bank that is easy to follow and easy to execute. Maybe this can become a sticky eventually.

I have been looking into this as well.
