To get credited you should contact me (which you just done now) in Private Message not in public It doesn't automaticaly credit anyone who donates, because not everyone wants to be credited.
It's not locked to euro, you can select own currency from the drop down menu, euro is only displayed by default.
I need your real name or email you used to donate, to find and verify your donations. Thats why it should be posted in PM, you dont want these to be seen aby everyone here.
