There are a great variety of new features to check out, all of which I've listed below:
Full Twitter and Facebook integration:
Twitter integration is brand new, and the Facebook integration has been repaired.
The great part about this is that you can customize exactly how much you want to share between the two accounts, as to ensure that your personal information stays private! And if you want to share status updates between two accounts one way, but not the other, that is possible! You can even do it on an update by update basis!
Connect your account to Twitter
Connect your account to Facebook
You will now see share links below each topic for sharing them on Facebook, Twitter, and a variety of other programs. Pretty self explanatory, but the process is made even easier if you have connected your account.
Upgraded Status Updates:
You can now reply to status updates! Not only that, but your profile now keeps a record of all of your updates, similar to what you would find on a Facebook or Twitter wall!
When you mouse over a topic, you'll now see this button pop up on the right.
Clicking it will give you a preview of the topic without having to actually enter it.
Youtube Videos Embed Automatically
Throw out that Media tag. You no longer need it!
You can now customize the background image of your profile! Be sure to jazz it up a bit here.
This link is visible when you click on your name at the top of the page, with a link also on your profile. Check it out.
Brand New Notification System:
This will give you a little non-intrusive note whenever someone does something like comments on your profile, or replies to you on the forum. Very Facebook-ish. Check out your notification history and options here.
There are some other updates that I won't be revealing yet, simply because I'll need to decide how I'm going to integrate them first. I will also be making slight color changes throughout the days.
Anyways, please enjoy, and if you have any questions concerning a new feature, just ask!
