The PROFIblog turns four years old today.  So, I thought it was time to state what PROFIblog is and how it is supposed to work.  About time, eh?

Merry Christmas and Happy Downtime

Happy Downtime! Downtime meaning personal time off to relax and recuperate as opposed to having your plant shut down unintentionally. I’ll be taking some time to enjoy family and friends, watch little ones open presents, eat too much (especially buckeyes – the candy, not the nut), and make some resolutions for 2009. Now I’m off…
