The issue with this was using multiple Google identities. The Google Container Extension would want to open any other Google sites in the same container.

I wanted to keep the soccer club administrator, school website, etc. Google identities separate and distinct.

Perhaps things have changed and this isn't an issue anymore. What I did was create an identity (soccer, PTA) for each gmail account and set defaults for google.com, YouTube.com, etc.

Having [email protected] is really nice for being able to give someone else the password and let them take over the account when your term is done.
