Just to be clear, I do understand that you said you were removing vandalism, and obvious vandalism is excluded from the 3RR. However, this was not obvious vandalism. I blocked the other party in this edit war for 24 hours, however, since you were reverting vandalism and tried to communicate with the other editor, I will only warn you. Other admins may disagree, and could decide to block you as well, as this normally is what happens in edit wars. If there are additional problems, please post at the appropriate board for other editor's input.
