Channel modes

These are all channel modes that can be set. Use the command:.

Normally you need channel operator status (+o, or some other level such as +h/+a/+q) if you want to change channel modes. However, IRCOp's with OperOverride privileges may bypass these restrictions. And similarly for IRCOps with access to the  command.

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.

Disabling levels
In UnrealIRCd 5 these are built-in modules that cannot be disabled. In UnrealIRCd 6 you can decide not to load a level by using blacklist-module, eg  if you don't want.

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.
