So on the server I have built a second Tardis and want to get rid of my old one but I don't know how. Help?

You will need to sell it to another player. Staff cannot physically delete TARDIS's. 

Ma11ux is correct; Staff are not allowed to remove players Tardises because they have crafted a new one.

...You have to sell or give it to another player using the command '/tardis-ownership [name]', and they'll also have to do '/tardis-ownership accept [number]' -make sure to be standing in the Tardis when you run the command.

Sorry, I stand corrected. -I've been told by Josia that that rule has been changed since I last looked.

GetMrBeaned, if a staff member is on the server when you are, can you ask them to remove your Tardis. If they say no for the same reason I did, please direct them to this forum post =)
