I've been Beta testing this resource, and I really have to recommend it for every type of Creative server. It get's rid of many stupid exploits and bugs of the vanilla creative mode that Mojang failed to patch for years now. It has a unique way of emulating creative as perfectly as possible within Survival mode. While it is certainly different then normal Creative, it is very familiar to it, and it even has some extra tools that normal Creative lacks. The developer, RockinChaos is a very friendly person, and even tough it might take a while for him to answer, he cares about his plugins and it's users and is open for feature requests, as long as they fit the plugin.
