+When you add a user to a new group, you're often told you need to log
+out and log back in for the new membership to take effect.  If you're
+at the terminal running [[screen]], this is no big deal, but it can be
+annoying if you're running a lot of graphical stuff that doesn't
+suspend and resume so easily.  Luckily there is `newgrp` which can
+adjust your current group ID to match the new group:
+
+    $ usermod -a -G groupname username
+    $ newgrp groupname
