I just wanted to give everyone a heads up.

I have moved the software running this site (and the other sites on my server) from a virutal machine to something called a Docker container.  From a user perspective, there should be no difference in the operation of the site at the moment.  However, this solution should be much lighter with the resource usage on my server which was causing me some problems.  It might even speed the site up a bit but I'm not holding my breath. 

If you notice any problems, please let me know.
