On Wikipedia, we have a banner that appears when someone edits our talk page. I think that we should take this a step further. I am involved in anti-vandalism, and when we warn people, one of the easiest ways for them to take out their anger is to vandalize our userspace. I think that when someone else edits our userspace, a banner, much like the "new messages" banner, should appear on the page. Something like this:

<div class="usermessage">Someone has edited your userspace. [[Special:Mypage|Click here to see the page.]] (PUT LAST CHANGE CODE HERE) </div>

I would have included the code for the "Last Change," but I don't know it. 

Also, this dialog in particular can only cover edits to your front page, like if someone edited User:Example, not if they edited User:Kornfan71/User Page. Having said that, most of the vandalism is usually on our front pages and talk pages. 

It would be great if someone could help me with the code that would allow ALL of our pages to be monitored by this banner and for someone to help me code the Last Change link. It will NOT have to include our talk page, since Wikipedia already has us covered there. Please help me out with this code by going to en.wikipedia.org/wiki/User talk:Kornfan71.
