Anyone with a Hotmail account would have gotten a e-mail with this link in it.
However if you are anything like me, you delete 99% of stuff from Hotmail without even opening it.
For the AS bit, an easy way would be to use shared objects. Telekinesis and Jerez_z wrote about that on this site. A more elaborate way would be to use cookies and/or save it to a database, but I think shared objects would work for casual users
Take this site, if you made your avtar a shared object thats fine for when you return, you can see your avtar, but you wont see anyone elses and they wont see yours.
So you would have to save the name/colour of ever pieces to mysql, then when ppl vist it pulls the names all of the movies and colour info out and loads them into levels.
