Force Supporter PayPal page on Initial Login With Easy Blogging and Buddypress installed?

Sorry if this has been answered b4 but I've scoured the forums and couldn't find my answer. I've got a WP3.0 and BP 1.2.5 install, the latest versions of easy blogging and supporter uploaded.

What I wish to do:
User registers and selects the "I'm interested in becoming a supporter" radio box on the sign-up form is directed to the supporter page with the option to accept or decline before going to the easy blogging wizard options page.

I think it's skipping this step now because of BuddyPress sending the user to main blog when they first sign in, so what strategies do I have to make this happen?

Thanks in advance for your help.
