Channel modes

Access levels
These are the modes that grant a certain 'level' to a user.

Note that often Services are used to manage +vhoaq lists in so called "access lists" or AOP/HOP/etc. Consult your services documentation.

IRCOp's with OperOverride privileges may also set +vhoaq, same for IRCOp's with access to the /SAMODE command.

List modes
These are so called 'list modes'.

All these modes take a nick!user@host parameter, like: +b *!*@*.isp.com. See also Extended bans for other syntaxes (eg: +e ~c:@#channel).

Channel settings
These are channel modes that configure channel settings.
