Last night I pushed a working copy of MyAvatarEditor.com live to the web. There is still a bit of work to do, especially regarding the guide and developers pages. That will be filled with time. Most importantly is that with the site live, and having the editor off the temporary beta page, avatar URLs will work for opening avatars and sharing them with your friends.
Additionally I've added a new page under a directory called "show" which will just show the character, full screen in the browser, without the editor interface. Example:
You may notice that depending on the shape of your browser window, the character will be seen either in full or just as a head. Clicking on the My Avatar Editor logo will open that character in the editor.
I haven't yet decided if this page will be integrated into the editor or not, or even how useful it is, but it's there for anyone who's interested.
