# User modes

Modes set on a user with `MODE <yournick> +<mode>`. Some are settable by anyone; others may only be
*set* by an operator (anyone may clear them), and a few are managed only by the server or services.

Modes `H`, `W`, `h`, and `s` may only be *set* by an operator (a non-oper attempt gets
`ERR_NOPRIVILEGES`); anyone may clear them. Which oper-only user modes a given operator may set is
further gated by their oper type's `usermodes` allow-list — see [Operators](/docs/operators).
