First off this thread is going WAY off topic. Second, there is a thread** about donations and upgrades in the FAQ. Third, if you have a specific question that has not been answered within the FAQ then ask by Email if you cannot ask anywhere else, then if it has not been answered on the board I will reply to your thread with the answer.
