You can now vote for the images that you like on the Oekaki. Just click the "like this" link that appears under the image to register your vote . Soon we'll put up a forum which has all the top voted images in it, but that feature is not ready quite yet.
We now have nice buttons for "New drawing" and "Color me in" so they should be much easier to find. It is now possible to color in your own drawing even if it is not posted to the Editable Oekaki forum, so if you want to make your own lineart that only you can use, you can post it to beginners and created colored versions from there . (of course you can still edit your own drawings as well)
