Internet Relay Chat services
Internet Relay Chat services (usually called IRC services) is a name for a set of features implemented on many modern Internet Relay Chat networks. Services are automated bots with special status which are generally used to provide users with access with certain privileges and protection. They usually implement some sort of login system so that only people on the access control list can obtain these services.
Components
The most popular style of services uses a number of fake clients whose names end in "Serv". The four below are nearly always seen in services of this style.
ChanServ, a channel service bot, is used to protect channel operators and help run the channel. This is convenient for the operators because they do not need to have an operator on the channel all of the time to keep their status.
NickServ, a nickname service bot, is used to register and protect user nicknames.
MemoServ, a memo service bot, is used to record and deliver messages to users who are currently offline.
