/WhoWas \<nickname\> [\<count\> [\<server\>]]
*
Finds out information about a particular user who has now left IRC. If \<count\> is given, only that number of instances are returned. \<server\> will enquire a specific server.
This may not always work dependant on the server and the amount of time between them leaving and you issuing the command.
