ISSUE WITH FACEBOOK LOGIN
UPDATE: Issue is resolved as of 10/28/2012
As of 10/26/2012 we are currently aware of an issue logging in with your Facebook account. Something that facebook changed / did has impacted your ability to 'click' to login using your facebook account.
This is being investigated and will be resolved. So please be patient for now.
Also use this as a learning point and 'link' more accounts (using any other service like Yahoo, Google, or any other OpenID).
We will update the website with a news post once this has been fixed and is back and working.
If you really need to get in using your facebook setup, please let the board know and we can update your linked in account to allow other account access manually.
Coincidentally, we have an achievement badge for this as well called 'Connected' that you can get if you connect 3 or more accounts.
