I do want to know who isn't responding to trades. That is a no-no. If a person doesn't want to do the trade, they need to reject. Letting it sit there is BS.
I'm not sure if I have missed anyone. I try to check at nights when I'm hanging out, but sometimes forget. I tend to do most of my pissing around on the interwebz during the day at work, and we have filters that won't let me get to the site.
