Guser
From Scriptwiki
This adds the specified nick with his address to the userlist with the given level.
/guser [-a] <levels> <nick> [type] [info]
This works the same as the /auser command except that it looks up address using /userhost on the given nickname and adds it to the user list. If no type is specified then a default address format is selected, being nick!ident@host).
Example
guser 2 Dana 2 This is Dana!
This Example would add Dana with its address (type 2 - *!*@host) to your userlist with level 2 and information "This is Dana!"
