Known issue.

Being addressed.

In the forums section here if you look up just below the Welcome Bushman on the silver bar you'll see My Account. You can change your personal images there and it will work. You can press ctrl F5 when your done and it will reload and update if your using IE. If not then logoff and log back in and it will update with your new avatar.

Not just IE, works in all browsers. That always works for me when I upload a new image.

It just never ceases to amaze me what you can learn just cruising around the articles.    Which I do have to admit I don't spend near enough time doing...

Has anyone posted a detailed article on the 'your site' page?  Like, for instance, how to get your favorite skin posted and/or how the site structure works?
