Even with this extremely
helpful guide with somewhat broken links, people ask questions about stuff covered here.
People think they can make a (decent) server from following guides, and videos, and reading this/other topics... They're mistaken.
Some people are gifted with enough brain power to code and make a server, and host.
While others, are better off just playing them.
People whine, complain, and flame over how people offer help, it doesn't work, the supplier says it does (it really does), the supply-ee failed, and whine some more about how it's their fault for supplying a faulty code, or spoonfeeding wrongly.
Simply put, tweenagers and such lack the brain power and general thought to make a server, and then cry and flame others for offering perfectly good help that they cannot comprehend.
