Yes. He said he'll start by cross-referencing the e-mail address associated with your Paypal account with the one you used to sign up with BFC. He'll next search by the name associated with both your Paypal account and BFC profile. If none of that pans out, apparently, he's gonna contact members directly.
Spark has all the info he needs to ship out the knives themselves, but the previously-discussed membership bonuses obviously can't be mailed to you, so he's going to use the above methods to sleuth out which members bought knives in order to apply those bonuses.
Thanks, but my PayPal email address isn't the same as my BladeForums email. I'm counting on his using the PayPal home addresses.
