Powers of 2
Sooo
1,2,4,8,16,32,64,128,256,512,1024 allll the way up to 2^32
So you can have 32 access levels....which is more than enough for most apps
(actually find 3 levels is enough). Word of warning, be wary of where you
store the usersecurity info a user only has to store 2^33-1 to get access to
all security levels. Where I have to have cookies, I do a check before the
display/updating of sensitive information. Otherwise I let them do what they
want.
