Mike,

I apologize for the late response.

You are pretty much okay without it.  The documentation there is actually 
lacking that there also needs to be a similar entry in $updateUserFunc.  If 
you try to look up a user that does not exist in your user table under "User 
Lookup" the site will generate an error without this entry.  Similarly, if you 
try to add a user that does not exist in your user table somewhere on the web 
site (i.e. adding a user to a user group), you will also generate an error 
without an entry in $addUserFunc.

As long as you always work with users that exist in your user table, you will 
not generate any errors.  Even if you do try to add a non-existent user, at 
worst, the code will just tell the user an error occurred (unless the user has 
rights to see debug info, and then the user will see the generated error).
