Minecraftore.org is depreciated and only left in for good measure. I'd suggest moving to openredstone.org. We won't likely keep paying for minecraftore.org for very long.
guys, I think there has occoured a serious issue on the server. Basically something some people would refer to as "ghost mode" which can also occour on singleplayer and usually fixed with a relog, but on the build server it seems to happen no matter what.
For anyone who does not know what ghost mode is, it is simply a faulty connection to the server where you can interract with it, but the server cannot interract with you. In this mode you can run commands, break/place blocks, etc. but you cannot open inventories/GUI's, pick items up, change your position in the world (you spawn in the same place each time you log in even if you moved), talk in chat, etc. I would imagine a simple restart would fix it, but I'm not sure. Either way, staff notice is required.
