You can set a default alias to be used in any channel that allows you to change your name. Users can be filtered out. Users can read files into party. Most channels set a line limit on that size of such files. You can also save lines from the party log into a file.
Users can configure party behavior in many ways.
You can also define arbitrary Unix commands as filters to feed all party output through. Idle users can be disconnected automatically. Each channel can have an idle timeout configured in. Party can be run as a secure shell. Normally party allows shell escapes, but you can turn them off so people running party can't get out.
