Now that the new sidebar/ad size has been implemented network-wide and SE designers are working diligently on remaking all of the internal ads for sites, I was expecting to see the community promotion ad questions pop up on the sites I use... but they haven't.
In a comment on that question, Abby said:
That's why the community ad refreshes have been delayed this time around - we had to confirm this plan, so we didn't make everybody submit a bunch of ads in the old size and then have to suddenly do it again at the new size.
As an FYI, when should we have our updated custom ads ready to go for the new season of Community Promotion Ads?
In addition, an answer that gives a brief on the updated guidelines for the ads would be much appreciated, too.
