I've been trying to figure out a way to do this and be fair about it without causing to much work for me. I thought of featuring the member with the most posts, then I thought that wouldn't be fair because some of us have more time than others to post.
So I figured I'd make it simple and easy for me and not to show favoritism but to be random.
This is what I came up with post your ad for your site or shop in this thread and I will feature them as they come in the ad box on the bottom of each thread.
If you haven't seen it yet when you open a thread on the very bottom you will see my ad and my wife's ad displayed.
I will put, at random, a featured members ad there to be displayed for a day maybe two depending on how many responses we get it may be there for a week. I will feature each member for at least a day, now don't get mad if someone is up there for more than a day and you were there for just 1 day, this is strictly random and as my time permits me to work on this. I will be as diligent and fair as possible, but I take days off too so don't be surprised if the display time is random.
Mine look like this:

Don't worry about code just post a 125x125 picture here in this thread with a link as to where you want the ad to link to and I 'll take care of it.
I hope this will get a lot of response as I know most of the members here have shops, websites, or blogs they want to promote and this is another way that my wife and I can give back to the handmade community of artists for free.
So post away and put your ad in this thread, the first one will go up right now! I hope you enjoy this new feature as I thought it was a pretty good idea.
Enjoy

Edit: as we go through the ads I will then go back and start again to keep a rotation, also depending on the response I may feature more than I member at a time, to show some extra love. This all depends on the amount of submissions I get. So don't be shy, I'm not!
