I've moved the chat window for a number of reasons, one of them being the time it takes the page to load. It hasn't disappeared entirely though. You can still access the chat window from the bottom of any page on SFN. Upcoming improvements may see it back on the main page, in the meantime though I'm going to show you how you can place the chat window anywhere you like on your desktop!
It's really easy to do, click the middle of the three icons at the bottom right hand side of the page, (you should be able to see it now) do it now, it won't affect this page or anything else.
You'll see a new window appear, you have now 'floated' your chat window. Notice that it is now completely independent of the website and can me moved and resized just like any other window, leaving you free to navigate anywhere else on SFN without losing sight of it. (You don't even need to stay on the SFN website at this point, provided that keep your browser open the chat window will remain indefinitely.
