It's great to be here - such a great answer!
Thanks alot for your useful and swift answer to my question, as said, this is such a great forum - dual-boxing rules!
I still have some questions though. You are right, Account 1 and Account 5 are not linked in any way. Unfortunatley, because i live in non-EU-switzerland (where because of regulations issues rectruit-a-friend is not possible) i will not be able to link them. I got Account 2 from ebay and the address is still listed as a "not swiss-adress".
Anyway, that leaves us with account 2, 3 and 4. They are linked, upgraded with authentification key but i did not yet set up a subscription.
Maybe that is the reason for the missing triple XP. Any thoughts?
You said:
"Ensure in the worldofwarcraft.com account management that your accounts are, indeed, linked. You can test it out by making new level 1 toons on all 5 accounts, grouping, and killing something. Toons on accounts 2-3-4 should receive a "+x from Recruit a Friend" message."
What did u mean by "+x from Recruit a Friend" message"? Combat log? Chat entry?
