I am currently in the process of updating and improving this site. Please pardon any inconveniences this creates. In the end, there should be more useful information and more fun stuff here, so please do check back.
In the process of cleaning up the site, I had to delete a large number of user accounts that had been generated by spam-bots. I apologize if you had a genuine account that got deleted. Please feel free to sign up again. (The main advantage of having an account is that it gives you permission to post comments.)
