You should be able to close the ad above for a month at a time, but for some reason occasionally it pops back on. Trying to find the bug now...
There are many other smaller upgrades as well. Most importantly you can see the winners on the contests including the closed blind ones as well. And the Make an offer button is now visible to anonymous users.
You can also delete a logo right from your manage page. We also have the pinterest button on logos, etc.
As always let me know if you see bugs and/or you have suggestions.
