Welcome to uselssknowledge. A useless community for people to share their useless knowledge. There aren't any rules. Or any purpose for that matter. We just ask that you be kind to one another. After all, all the info in here is useless. So no calling people, or their knowledge, stupid or dumb. We're hoping that what might be useless to some, could be helpful to others. So there are no topics. Just post what you like. Hopefully some of you will learn a thing or two about a thing or two.
