How do I get the extra 500 MB for a referral?

Hi freddie3, thanks for bringing this to our attention.

When you used the link to download the Dropbox desktop application, were you downloading it from their home, from the same network he uses for his own Dropbox account?

This will help me to assist further!

Yes we were at his home. he was helping to set up the computer.

Thanks for the info, I've sent you an email, please could you reply to it when you get a chance?
If there's anything else we can assist with, feel free to reply back here!

I tried to reply and it was first refused by your email server as spam and told me to resend the message, then when resending got a message back that the mailbox was unmonitored:
