Thankyou. This is now resolved. I am able to login today. Presumably, I was indeed kicked off and being unable to connect is what happens in those circumstances. Makes sense, thought the "Server Error" message you get is a bit confusing.

Hi, I cant seem to connect, but my son can. Was I kicked off? Is that what happens - you simply can't connect and it says ?? Would you get an email or something? All very confusing. Could it be something to do with this -- I connected a couple of nights ago for first time onto the new server to check it out. I warped to home and was walking around my protected area. Then I jumped up a few blocks and got stuck and started getting messages about anti-cheat and flying. I was glitched and I don't know anything about flying or why I would want to. I then logged in again and none of the chat commands would work. Is this what happens when you are kicked off, or is there something wrong with my minecraft client or account? Thanks Gavin Rose

I was thinking the same thing - want to have a pressure plate when entering a room that activates jukebox via redstone. Thinking that this could also circumvent the problem of not being able to protect your records/discs in the jukebox -- i.e. you could then hide or encase your jukebox with disc inserted and any visitor could trigger it via the pressure plate or a switch. The plug-in to allow redstone control of jukebox exists: https://github.com/eXeC64/JukeboxControl cheers, Maestro
