Hello there 
I want to share my nick tracer with you:
It shows all nicknames a host has used on join.
But you can also see all nicknames a host has used by doing /whowas nick or /whois nick.
Bugtracker: bugs fixed.
Changelog:
New commands added:
/user.check <nickname> - shows all nicknames a nicks host has used. Nick MUST be online!
/host.check <host> - shows all nicknames a host has used. Please use *!*@host.org as format.
/host.del <host> - Command /host.del <*!*@Host.Com> deletes all nicknames refered to the host including the host. Please use *!*@Host.Com as host format. Attention! If a user with the delted host joins a channel where you are in, the host will be added again.
/nick.check <nickname> - shows all hosts a nickname has used in the format Nickname!Ident@Host.Org.
/nick.del <nickname> - deletes a nickname including all host belonging to it. Attention if a nickname joins a channel you are in, it will be added again.
/user.add <nickname> - adds a nickname to its belonging host which it is using at the moment. Nickname MUST be online.
/nick.add <nickname> - adds a host to its belonging nickname. Nickname must be online.
Part ONE: http://pastebin.com/YXnphAPR
Part TWO: http://pastebin.com/RhptNqX7
You HAVE TO USE all parts.
Please use for each part an extra/other remote/script window. Do not paste both in the same remote!
