Not really true. Its effective after someone have called setgroups,
which is done as a part of the login process, (on linux usually by a pam
module).
If you add yourself to a group, you only are usually just changing a
textfile, which lists which users belongs to which group.
There are other ways to change the groups list for your session, but
none that i can recommend to non-maniacs =)
So, the only sane recommendation is to logout and log back in again.
