Do you use Hive Keychain to log in to Ecency, or just your posting key?

The Ecency wallet may also have an option to view resource credits, but I can't find it. I don't think need to sign in to PeakD to view public ledger actions, including resource credit delegations. That's one of the nice things about the HIVE ecosystem. Different frontends simplify different tasks, and they're all interconnected with the same network.

EDIT: In your Ecency wallet, click in the blue and orange RC bar under your profile information. It shows a link for your delegations in or out there.
