Re: Sold Ads Widget
you can already mark your ads as "sold" by clicking the pause button. I've modified a website recently to say "SOLD" when users pause their ads.
While the software may be able to use some more features in this area, it might spark you interest to know if you poke around the code a bit you could probably figure out how to use the pause button to show "sold" on items.
writing the wordpress query code to pull only sold items might be interesting though since "draft" status could mean exipired, but its obviously possible because the dashboard somehow figures out whats paused vs whats awaiting payment.
Anyways, I imagine we will probably wait until Wordpress 3.0 comes out since there will be a new array of post types, we will probably be able to move between post types, "sold" posts being one of those types. Just a guess, we are still many months away from this.
