Now that Christmas is over and things have quietened down again I've had a chance to sit down and perform a few more updates. So this evening I have uploaded the following changes to this site:

1. A list of tags has been added to the home and blog pages. When I create a new post I will now tag it with certain keywords so users can find old articles quickly by using the tags
2. The user account sign up page is now complete and working

There has also been numerous other very minor tweaks that aren't worth mentioning in great detail.
