This Modpack aims for making servers much more fun and smooth.
It is allowed on most servers but you should make sure so you don't get banned.
Some of the things that this Modpack includes are:
journeymap, to keep track of places you've been,
just enough items, so you don't forget recipes,
mo' bends, to make Minecraft look cooler,
and other mods to make it easier to see data.
I use this Modpack almost every time I play a server.
It is extremely fun.
