Exactly mithrandi, I have to agree on what you are stating. Dargo's explanation sounds logical and believable enough, and there is no reason to assume he is making up something.
I especially agree with the point Dargo made about to wait until FIBOR fixes the current API dis-functionality on it's backend, instead of messing around with manual deposit/withdrawal processing.
Manual processing would certainly lead to a significant number of human errors, which would cause more/longer delays, and as we know - there is not enough support staff to handle that in a timely manner.
Dargo keeps us informed which is great. As he is in direct contact with Kraken clients in this forum, he is in a position to transmit important info's from clients to kraken management / departments.
Let's help him in the best possible way, as this helps all of us.
