After posting my issue on Facepunch and having a guy getting it fixed my Minecraft is fully fixed and so I'm going to be hosting my server again! All the members of the group please join the new network (I deleted the other one...). Same name and password.

I'm trully sorry but after updating my drivers it messed up my Minecraft... long story short: I can't play it anymore. So don't expect the server to be up again. Though if it does, I'll be extremely happy to announce it :D

As CraftBukkit hasn't got a new version compatible with the latest Minecraft update, there are no commands or features related to the plugins that were avaiable before.
They should be avaiable when CraftBukkit is fully updated. Until then, you can still enjoy the server! :D
