Times are Changing…

A long time ago I abandoned DotNetNuke and began porting sites to Drupal, unfortunately, this ended up being a bit of a disaster (no, I’m not a Drupal fan) and sites like this one were ignored for quite some time. Finally, I got my act together and ported the sites yet again over to WordPress – and so here we are.

Times have changed since I first wrote this site and it is about time that it received some updates. The updates have already begun – but expect to see much more extensive updates over the next few weeks. I’ll keep you informed.
