We have a T9K tekkit server?
Since when?
Not exactly t9k pre-se... its hosted by various members whom have teh skills.
Tekkit is fun when you disable the "creative plus" mods like (in)equivalent exchange that allows you to generate a near-infinite amount of whatever material/block you desire.. You might as well forget learning how to use pipes and elaborate setups with various machines and electricity.
Some items also really stress the server like "world anchors" that keeps chunks running while un-inhabited by players.
Still, the best mod out there... support your favorite modders respectively by giving them your monies because its a collaborative effort and things.
