I don't like having accounts but sometimes we need them, so let's make this as painless as possible...
Path of Exile Account:

This is optional and currently provides no benefit. However, I'm putting it here because I'm going to be implementing features which will make finding your own data easier. When supporter packages are available this will let me know which accounts to give recognition too. You will be able to set or change this value at any time once the user control panel is complete.
