How do I loop through all the users in my Telligent community?

How do I loop through all the users in my Telligent community?

I have tried the following, but it is only returning 20 users. 

#set($users = $core_v2_user.List())

#foreach ($user in $users)
...
#end

Is there a maximum PageSize? If so, how do I loop through all the users?
