1) Don't go mad activating all plugins!

It is neither useful nor advisable to activate all plugins. No server requires all the plugins we have on the system. What's more, some plugins offer the same functions, which will then cancel each other out. The result will be plugins that don't work.

2) Think about what you need beforehand!

If you just want to protect your chests, LWC will serve you well. If you just want to use warps and homes, Commandbook is the plugin you need.

Basically:

The fewer plugins the better!

A normal server that covers everything you need has the following plugins active:

LWC

Commandbook

WorldEdit

WorldGuard

 You can cover the needs of every server with these four plugins.

With these you can protect areas of your world, protect chests, and create warps/homes.
