The integration is entirely internal, so it would be tied to your current forum account
Those that pledged through Paypal are already integrated and why you see some have a Backer title, Founders can ask to get their title a bit earlier by messaging us on Kickstarter, yes.
Basically the problem is, Paypal is already integrated into Xenforo (the forum software), and so it was relatively easy for us to get started on that. Kickstarter however is not, and so we have to make our own system and that will take some time. Add to this, not all Kickstarter money have been collected yet, so we are still waiting on the final data.
