I got a killer way for the site to keep track of lost icons that the user forgot to assign an email.
You know how websites keep track of IP Addresses right? well in the editor online window it should state your IP address for the website, and then if you accidentally forget your email you can just copy in your IP in a verification area for the icon, then if the IP matches the source, it will be accepted and thus, placed under the user rights.
Only problem is that proxies wont work with this.
