I have asked KVS what GTC credentials are and why I need them. No response. I have had a subscription to KVS for a long time and I don't understand why I have to register again with a social media site given.

Is there any advantage to staying with KVS rather than switching to Expert Flyer? You pay for something and you expect it to work, not to demand more information from you.

I have had several emails from KVS and he keeps telling me to register for GTC credentials but doesn't tell me what this is all about. I find this very strange.
