So, 1st off a new popular list came out this month. This time it was only for worlds being updated. No new worlds were added. If you submitted a world last month, it will still remain on the submission list to be reviewed for next month's list.
David N., the owner of Eden Elite has been working hard on improving the popular list system. He has made the submitted world page look a lot nicer, and he has also been working on other things like a voting system for a fair ranking on the popular list. Also, he has added a feature allowing you to submit an update to a current world already on the submission list. This will come in handy if you submitted last month.
Lastly, the date list has been removed. The reason is that people have been using it to chat which is causing too many worlds in the database that are not real worlds. The list will most likely be replaced with a suggested list or a classic world list.
I just did. I've been checking that site as well besides just this one and the edenfans one. I scout around trying to find really ellaborate worlds that I haven't seen and explored yet. Oh and thanks for answering my questions I'm especially pumped for the Suggested List idea
