need help - Usergroup is set to whitepage with error

[gsmworldone]

this question is almost the same with my older post
because, in my older post is only asking HOW to add usergroup to member
that in userrank stars will not appear to there profiles,
so that other members will not recognize the new added usergroup for it.



NOW FOR THIS THREAD
instead of banning a member
they will add additional usergroup for it
called WHITE SCREEN

so if that member will login in the site
"" white screen page with error message will show only ""

this is nice technique of admin,
member's profile is still good and fine,
but deep inside is that member is "" CAN'T LOG IN ""

nice right? member will not get mad,
only thingking is slow connection of internet
but the truth is admin set a additional usergroup "white screen"



why i'm asking this is all i want to know
is how to do that usergroup of white screen page..?
pls help.




thanks in advance
