Hello Wikimedia,
here some people have posted some thoughts about the problem of anonymous posting.
I have experienced it too. For me it looks like that: I have posted answer on the Talk page, while being anonymous, so system has fixed my IP address; from my answer it is perfectly seen that it was me who posted it, so everyone can for sure identify me and my IP address. And, for now, everyone can see my IP address in history of this page.
But it was supposed that my IP address should be private in wikipedia. since it's static, it is not private anymore in any way.
For now for me it is not very terrible problem; but I think it could be for someone or for me in some time!
What could we think of to solve this problem with privacy?
My first proposal: after I am logged on, I should have the option to disallow my IP address from anonymous posting. So when I am on wikipedia once again, anonymous, the system won't give me the possibility to save changes without logging in (or, may be, pushing explicit button "I want to edit without logging in, with ip-address logged").
