Ignore stuff

Say you want to ignore all those

foo ... has quit
bar has joined #channel

and so on.

You can use the /ignore command. E.g., if you want to ignore all the joins, parts, and quits of #vim, issue the following command:

/ignore #vim JOINS PARTS QUITS

You can ignore more stuff, like actions, kicks, and similar. You can also ignore particular nicks, hosts, and even arbitrary text matched by a regexp. See /help levels and /help ignore

Finally, you can unignore stuff, for example, ignoring all joins except those from ikks.
