Forums mIRC Help How to unignore a user

So I did this

/ignore jtv!*@*.*

Now I want to undo it, and /unignore jtv!*@*.*
keeps saying

UNIGNORE Unknown command

/help /ignore

/ignore [-lrpcntikdwxu#] <on|off|nick/address> [type] [network]

The -r switch indicates that the address is to be removed.

You can also just bring up the address book and remove it manually.
