Linuxconf can create and manage various types of user accounts. Regular login
accounts allow users to manage files and access system programs. PPP
(Point-to-Point Protocol) and SLIP (Serial Line Internet Protocol) accounts are
accounts for users who dial in via point-to-point serial line connections. UUCP
(UNIX to UNIX Copy Program) accounts allow for file transfers over direct serial
connections or modems. POP (Post Office Protocol) accounts are for users who
retrieve their e-mail from POP e-mail servers. Virtual POP accounts are the same
as POP accounts, but they're used for virtual e-mail domains.
