We've changed up the keyword / tag system so that it is a little easier to use.
Now you can directly input your hashtags in your image caption / description. These are picked up automatically and associated with your images. You can also link directly to a user by using "@username" in the image description.
Lastly, you'll find some minor changes to the homepage. You can now browse all of the latest images on MuseCube, in addition to those from people that you follow. And we've also made it a little more pretty.
