A few updates for you guys on everything going on behind the scense.
1) Chat function - currently there is a chat available by clicking the "Chat" link in the menu. You can also scroll to the bottom of the home page to access the chat as well.
2) A light version is still being worked on but you can use it at your own risk by selecting the "Primary - Light" theme in the theme selector at the bottom of any page.
3) PDF attachment quota has been increased (thanks to @zag)
4) Social buttons located below the announcements. Make sure to like, tweet, plus, etc. Every bit helps with building our community.
That's about it for now. If you have any questions, ask!
