But Microsoft and even NeoOffice have password protection under basic "Save as" options. This seems like a fairly basic oversight to me. However, thanks for the suggestions above, I'll look into it.
Also: Does this strategy mean I'd have to log out and log back in as the other account just to read a document? It's mainly just me on this computer. If I set up a special business Account called "Records" or something for all those business passwords, and I wanted that file password protected.... how do I set the privileges so that only the "Records" account/password can read that file? I've looked under Command i and can't find it.
