[Plugin: Register Plus] DOing something with invitecode

Hi

I would like to show a page accord?ng to the entered invitecode is there a way to do it?

I know you can reach then by creating a database search.

I want to show a special welcome message (A wordpress page) for every different invitation code. Can this bi done in an easy way can i recall the %invitecode% when an user logs in after registering..

Thanks
