Will you accept my challenge?
I'm challenging every deal poster to do this simple thing. It's really, really simple. Go into the deals section and click on your name to display all of the deals that you've added. Go about a month back in your added deals; now do you see that "expire" button by your deal? Click on it, then confirm you want to expire it. It is that simple! Now repeat that last step for all of your deals that are expired, or at the very least a month old.
Seriously, if you have some time today please go through and expire some of your dead deals. It will help your rep, and help out the DW community.
