Yeah its definitely a good idea to protect you, your stuff, and your home using towny on the PVP. At the moment.. The non-grief server is currently up and running, there may be small periods of downtime here and there while im updating or changing things, but I think its mostly runnable at the moment Feel free to give it a try.
Server information is in the forum at the enjin site. http://fbitekkit.enjin.com
