BINGO! Found it. Corp->Corp transfers do not show as "Player Donations" and due to the huge number of transactions in our corp journal, that's what we look for. I've sent the 7 million back to slaw - next time I'll know to check specifically for "Corporate Account Withdrawl" transactions. (That's what it shows on my end, though it's actually a deposit; go figure!)
Cheers
sanfrey and spinward, thank you for your attention.
although I tend not to let money stand in the way to enlightenment, your funds did not arrive yet back to my account.
I will also appreciate getting access to the course materials.
cheers
