Here’s a great resource that has something for everyone. I thought I had come up with a pretty comprehensive design resource list when I posted Creative Alternatives and Resources. This is an amazing listing of links for designers and developers alike.
From working with Ajax, to XHTML character references, the link list given on forwebdesigners.com is pretty comprehensive. Some of these links you may have seen before, but alot are new to me. They even give you a link to suggest a link they may have missed. I have definitely bookmarked this site, you should too.
I’m sure you will find something useful – 332 helpful links for Web Designers
