You could easily create FAQs storing that information.
You could easily create tickets storing that information. (and if you used an email address that everyone knows, but isn't a real address, any of your staff would be able to get to them).
Otherwise you will probably have to wait until 1.8 which may have user accounts baked in so that you could then create custom pages and possibly associate them with user accounts.
Finally you could add your own text block and have it store whatever you want.
