I discovered something today when working on a secret project, and thought I'd share it with you. There is an online service called
Minotar which basically just gets people's skins. You can use these though in a variety of ways. One of which, is forum profiles.
If you go into your options, and select "Specify bu URL" and enter the following, obviously replacing my name with yours.
https://minotar.net/helm/luisc99/180.png
This will automatically update whenever you change your skin. Also, it works with the new 1.8 format
Don't know who will use this, if any, but it's out there if anyone is looking for a profile picture
