In case you don't know, every registered member of WinCustomize gets their own personal site, with their own url. Your personal site displays some basic info about yourself, images of yourself and your desktop, your gallery on WinCustomize, and you can add your own links for display.
For an example, check out my site: islanddog.wincustomize.com
You can also see my site has a guestbook where people can leave message, and you can see a list of my current articles and a preview of some of the skins I have in my gallery. Personal site are a great way to promote yourself. You can put your site url as your forum signature in other forums, put them on your blog or social network page. You can get a lot of exposure this way outside of WinCustomize, and it's an easy way to show off your work to others.
I wrote an article a while back detailing how exactly to setup your personal site if you haven't done so already. I'd also like to give you the opportunity to list your WinCustomize site here so others can take a look at it. While we are at it, what types of things would you like to see added to the personal sites?
