Tip: Want to change your Avatar from your Facebook profile pic?

One of the things I noticed about the Login with Facebook option is that it overrides the Avatar in Dobbs. If you try to edit your Avatar, it seems "stuck" with the Facebook one and unless you change your Facebook profile picture, it will not work.
If you want to revert to a custom Avatar, here's how:
After logging in to Dobbs, go to the WordPress User profile page
You will see a Dissociate from Facebook button.
If you click on it, your account in Dobbs is now unlinked from your Facebook account. You can now manually edit your Avatar in Dobbs.
If you Login with Facebook again, it will link back to your Dobbs account.
