Professional Organizations

I'm thinking about joining a professional organization for illustrators. I'd like one that will hold workshops or conferences and give useful information about marketing yourself, networking, insider tips...etc. What organizations do you belong to? Do you find the membership useful?

New Website

Hope everyone is doing well! No posts in a long time so I assume we're all busy busy with work. I know I am. :o)

Over the summer I took an HTML class to learn how to make my portfolio online. It was very basic because I am still very much a beginner in regards to web design. The first site was ok, but I know I will always want to improve it every few months. This weekend I redid the site and am looking for feedback. FYI, this is all HTML and CSS using basic Notepad. I don't know Flash or Java, and I don't have any new versions of Adobe products (yet).

The address is: http://www.lindsayjohnsondesign.com

I'm specifically looking for feedback regarding:
-layout
-ease of use
-that the text is all written in clear language
-suggestions for improvement

Thanks in advance!
