RealIRC nick registration service allows users to register a nickname by providing a password, preventing other users from using it. NickServ registration is required for such things as registering channels and sending/receiving memos.
Chanserv, RealIRC channel registration service, supplies users with a way to secure their channels from takeovers. Founding a channel gives a user the right to add and remove ops and akicks, lock channel modes, etc.
MemoServ allows users to send memos to other users with registered nicks even when they are offline. Memos can be sent to individual users or to all ops in a specific channel.
