Thanks for your work on this. I think Liam123 has paid us a great service. He has been annoying enough to make us address the issue, but has given us space to talk about it and work out how to respond. What we do know now is that we need a clearly publicised protocol about the process reporting vandalism, approving a revert and then getting the revert actioned quickly. For this instance I suggest that we use the wiki page to divi out the task of manually reverting things (Potlatch willing). I will lay 'claim' to about 6 change sets and request that other people do the same until we get the job done.
