The new /ignore command is now available. You can ignore nicks (or hostnames), using regex.

Note: this command will be improved in near future with more options.

Some exemples (you can find them with /help ignore):

• ignore nick "toto" everywhere: /ignore add toto
• ignore host "toto@domain.com" on freenode server: /ignore add toto@domain.com freenode
• ignore host "toto*@*.domain.com" on freenode/#weechat: /ignore add toto*@*.domain.com freenode #weechat
