Thanks so much for choosing to support me by donating to receive the 'Pro' edition of Bandwidth Monitor. You're free to pay whatever price you're happy and able to pay, I only ask a minimum donation of $2.50 (about £1.70, for the British folks). Reasonable, right?
If you're planning to run the software on multiple machines, please take this into account when you donate. If I see thousands of serial number registrations from a single $2.50 donation, I'm likely to invalidate it. Play fair, is all I ask :-)
Your serial number will be delivered to the address used in the PayPal transaction, so make sure you actually have access to that inbox.
