Well, What about buying rocks. Some rocks in a mesh bag I saw today in Dollar General didn't sell so they were on the DG discount shelf.
Regarding putting someone on the "ignore" list. I know how to do it but what does it do? How does it affect your posts or how does the ignore work?
Instead of seeing a post, you would see the member's name, and a message to the effect of "user ignored"--something like that. The same thing applies to the "new posts" page. If someone you have on ignore starts a thread, you just see a small print message saying "user ignored." You can click on any of those messages and see the post or the thread anyway. That, of course, would rather defeat the point of putting someone on ignore.
