This site does not collect personal information from regular users. It may collect browser and IP info, but we won't use it for identifying you. We don't even know how to do that.
If you have a login ID, all your changes are being tracked, all the time. So if your login ID is "ralph", every time "ralph" makes a change, we will see it. We do this to maintain quality. Every change submitted to this site is checked, and can easily be reverted if the information is incorrect.
