[edit] Features
IRC server features, mostly extensions to RFC 1459. Probably also implementations of RFC 2810, RFC 2811, RFC 2812, RFC 2813, and possibly IRCX.
- +channels (named channels).
- #channels ("+channels" were later replaced with "#channels" in version 2.7, numeric channels were removed entirely and channel bans (mode +b) were implemented.)
- &channels (irc2.8, those that exist only on the current server, rather than the entire network)
- !channels (irc2.10, those that are theoretically safe from suffering from the many ways that a user could exploit a channel by "riding a netsplit"; IRCds using timestamping provide (most of) this functionality on #channels)
- %#channels (#channels whose name are in UTF-8 for IRCX)
- %&channels (&channels whose name are in UTF-8 for IRCX)
- %!channels (!channels whose name are in UTF-8 for IRCX)
