I did it again.
I accidentally hit the "start chat" tab again.
And couldn't remember how make it go away.
I've had this problem a few times before and have to re-learn it every time.
For some reason, I'm always under the impression that the solution lies under my profile settings.
It does not.
So now there is an article to remind me, and anyone else who needs it, how to get rid of this dang thang.
Step 1: Under the "contacts" tab, click "I am online." The words, not the pencil. If you click the pencil, it will complicate things and you'll have to reload the page.
LET ME OUT
Step 2: Click "Log out."
Anddd we're back to normal. Carry on.
It's not the most obvious way out, but it's easy once you finally remember how to do it, so I hope this helps cut down on some frustration. (If not for you, at least for me next time I accidentally open it and frantically search for a solution. =P)
