You don't need to reboot. All you need to do is login again, and your
session will have all the new group memberships. Group membership is
only set at the beginning of a session; ie at login, so to see any
changes, you need to start a new session.
Actually, you seem confused as to the difference between logging out and
rebooting. Rebooting is a drastic action on a multi-user server,
involving halting and restarting the whole OS and everything running on
it. Logging out and back in again is pretty trivial, and only affects
your own processes. Very different actions.
