I did not see if there was an answer about the trickle up affect. If you have 3 accounts and they have a single link between them ( A -> B -> C ) and then you grant say 30 levels from C -> B. The now level 30 character on B would be able to grant 15 levels to A right? (So getting a character to level 60 on account C gives you 30 levels on B and 15 levels on A?)
