I'm looking for either this exact plugin/widget, or something similar - look at this blog's right hand column for the 125x125 ad blocks with the "click here to advertise" feature: http://yoast.com/ He made a blog post about this plugin in 2008 and as you can see from the comments, a lot of people want this thing and were asking what happened to it - obviously the project was scrapped. I sent him a message on Twitter about it and got no response. Does anyone know where I can get something similar to this? Searched Google and found nothing.
You don't really need a plug in for that. It's just HTML using either table or div's, but here is the plug in that does it for you: http://wordpress.org/extend/plugins/wp125/
Thanks hmansfield: according to the reviews, it's broken for Wordpress 3.0 I'll try it out to see what happens.
