This is the old Item Lottery: http://forum.toribash.com/tori_lottery.php
I'm not too sure if it doesn't work, or it just isn't used anymore, but it kinda just needs to be removed—that is, unless it's being worked on. In that case, bring it back! It looks like an incredibly easy way for the staff to regulate the amount of tc circulating within the community.
If anyone has any suggestions on how to revamp it, please post them down below! I'd be happy to edit them into the original post.
Just to clarify, I don't have any clue how long it would take to revamp the item lottery. If a site developer has any insight on this, please give it here. It'd be awesome to know!
