Today is SysAdmin Day.  What, you do not know about SysAdmin Day?

SysAdmin Day is celebrated once a year on the last Friday for July.  There is even a web site which advocates this celebration and provides some nifty gift ideas for them.

So go find your sysadmin and let them know how much you appreciate them with a great big hug. :-)
