Hello Woohookitty, I am not only aware of the rule - I expect you to show those who violate against now the same courtesy you have shown me the last week. 

Unfortunately, this means you'll have to spend some time going through each edit to see exactly who has done what. 

When you've done this you'll know that Peterklutz first edit amounted to a smallish  edit of the previous edit .

What has happened since is that two persons has taken turns reverting Peterklutz edit.
