Q: Does colloquy have a way to ignore/hide parts, nicks, etc in a busy room? A: Colloquy does behave much better with no join/part event messages. There is no preference for this yet, but you can do a CSS trick to disable all event messages. This requires the nightly build. When using a custom style Variant, Option-Click the Customize button in Appearance Preferences. The CSS file should open, then add:
.event {
display: none;
}
Now type "/reload style" in the busy room. All the event messages will disappear and no new ones will show up.
