$level
From Scriptwiki
Finds a matching address in the remote users list and returns its corresponding levels list.
$level(nick|address)
The levels will be returned as comma seperated list. If it is no general access level, a "=" will be infront of the level.
Example
auser 1,2,3 Dana echo -a $level(Dana)
This example would at first add Dana to your userlist and then echo its levels. The result would be "1,=2,=3".
