When using the Live Map, clicking on a vacant plot (highlighted in blue) will bring up a white box with the res number and instructions for how to claim it. If you're using Internet Explorer, I recommend switching to Chrome or Firefox as the Live Map doesn't work properly in Internet Explorer.
Ok stu, the correct procedure to have taken in this circumstance would have been to appeal you ban in a private message with whom ever banned you, you could have also included the name of the other person with this evil machine there as well, that would prevent other player including the person you are claiming has a gen too from seeing it. If you need help with how to message a moderator or admin privately just ask me anytime, im more than happy to help you. Regards MR2R2M
