I believe (98% sure) yes. But if I were you I'd use the same mail, just in case. Personally I used the same.Does the donate button on the "Donate Help" page mark which Twinstar account is donating?

There is a unique link to paypal in Donate help so I guess it doesn't matter which email you have.How do you tie the paypal donation (which may use a different email than the one used on the Twinstar website) to the Twinstar account? Does the donate button on the "Donate Help" page mark which Twinstar account is donating?
Thanks.
