I'm not able to follow the steps defined here:
https://sites.google.com/a/chromium.org/dev/chromium-os/developer-guide/gerrit-guide#TOC-Googler-Link-chromium.org-google.com-accounts

I see the following error message when trying to confirm my google account (step 3):
Error 422: Identity 'https://www.google.com/accounts/o8/id?g=AI2Pq9qB_oFxl-gz_B0stYqiUJGahJDo1xteqnfCU7Qsh61xlNyO2DI' in use by another account
Endpoint: /config/server/email.confirm

However I was able to link my chromium.org account to google.com account for gerrit internal review. I'm not sure whatcaused cause the difference.

Thanks.
