I have NO idea if this will actually show up anywhere, but...
When I go to the Roku site (roku.com), I have to log in. I give it an email and password, and as near as I can tell I'm logged in.
Then I click on Community Discussions and get a line that wants a username for me to REGISTER. In my password set, I HAVE username. But when I put it in the field it says that name is already taken. I can't find ANYWHERE to log into the community discussions, and it appears my Roku login doesn't do it.
----------------------------
Since this showed up, SOMETHING worked. Except I'm not logged into roku.com, and the name I gave the community isn't the one I've used in the past.
