What is an easy way to save/load settings? I\'d prefer it if each user has their own set of settings.
This would depend a lot on the type of application.
If this is a desktop application you could save information into the registry in the user's area. Or into their User directory on disk. If this is a web or server application, you would need to store it into a database keyed by user, or to a disk file named for each user or something.
Since you mention options, it seems like the client path is more likely.
