Can someone tell me a simple plugin that create a different inventory between a group of world and another. If you know one (or can create one), please let me know.
It's sad to see how many users don't use the search function http://dev.bukkit.org/server-mods/multiverse-inv/
I'd also mention http://dev.bukkit.org/server-mods/multiinv/ Tux has taken on the maintenance of it and it seems to be working quite well. It can also import from some of the other projects. I looked at MV-Inventories but it didn't seem like anyone was really focused on it (or willing to interact with commenters). Tux has been quite responsive.
