Website-building Links
Web Hosting, DNS etc.
Namesystem. .com, .net, and .org names for $12 a year. Good DNS management options.
Dot TK. Free URL forwarding service for you.tk. You need 30 hits per 90 days though.
co.nr. Free you.co.nr forwarding. Requires only a fairly unobtrusive linkback on your homepage.
eu.org. Completely free domain names, you.eu.org but you must already have DNS.
Granite Canyon. Free DNS but no help provided so could be tricky to set up.
Zonedit. Free, easy to use and fairly fully-featured DNS.
XHTML Tutorials
W3Schools. Good XHTML reference with list of all the elements and attributes.
Simon Jessey's excellent introduction to XHTML for beginners.
Dave Raggett's introduction to HTML gives a good overview of the basics.
Development Forums
Devshed. Forums on everything in web design from Javascript to PHP and mySQL.
