AS YOU KNOW, all my characters I would give PGH to already have it, short of any more characters coming in who would make that more relevant for them to have. So I reserve the right to sign someone up later >.> but as of right now I don't think I really have anyone who I would give PGH too.
I -have- been thinking of updating Daisy, though, so if you end up needing someone else to sign up, she could volunteer for the experiment and just end up with canon memories instead of other game memories.
