I have just made a minor patch release of this site (to 5.1.3), the main fix being the registration controller which was not working due to some new code I'd added to the parent class, which was checking for a condition which was never met. If you have tried to register to this site in the last few weeks, my apologies for the downtime!
The main benefit of registering at this stage is if you ever want to comment on any of the articles presented here on this site, you can do so by simply providing a username and email address (for validation only, sorry no spam!), via the following form:
As stated previously, a forum is also planned which you will also naturally need an account for.
Updated 2021 : note that the above post is out of date as it was originally published in 2007, but is left here for archival purposes. Comments are no longer supported on this site.
