This is a plugin which was modified by SkinRestorer. The limitation of skinrestorer is that everyone is using a skin from a premium user or upload by themselves.
The process of uploading skins are difficult, while you have a lot of servers or having people making server together. The skin management will become difficult.

The plugin is currently in private, but our site is open for register!

Based on Blessing Skin System, we can use a single modified plugin to control the skin by web. You don't need to set your skin while you join a new server.
