Thread:Feedback/Autosignatures exacerbate the editing while logged out problem.

A long-standing problem with mediawiki is that it's easy to leave a reply while logged out and thus end up disclosing your IP. LQT makes it worse because you can't change the auto-signature after posting.

One solution: When an anon leaves a comment set a cookie with a secret value; when they are logged in, iff they have the right secret value allow them to hit a button which reattributes the anonymous edit and leaves a mark in the edit history to indicate that it was re-attributed (but doesn't disclose the original IP). The button could be displayed next to the anon-signature and next to the history entries if you have the right cookie. This wouldn't have to be a LQT specific feature, but I can see LQT increasing the demand for it greatly. Even if the cookie only persisted for the session it would help a lot.
