Methinks a tutorial added about setting up your own server at home to handle your webpage would be cool :P
Then you only need to buy + register a domain name and point it to your home server. This adds complete and utter customization at your disposal. One could download Apache, or go with coding a webserver from scratch. A drawback of course is the cost of good hardware for building a decent server, and the electrical bill for running it 24/7 hahah
EDIT:
Add some tutorials on the basics of PHP perhaps? But what I think is more pressing are CSS tutorials
Nice site though!
