To do that, you would need to modify the page history of every single wiki page you edited. From a user perspective, that would involve Doing this process manually would be so tedious to the point of not being worth it.
 * 1) Special:Export the page with full page history
 * 2) Edit the XML file on your computer to reattribute the anonymous edits to your account
 * 3) Special:Import the page (need to be an admin to do this)
 * 4) Repeat this process for every single wiki page you edited anonymously.

A bot might be able to automate that process, or perhaps there is a special server-side tool that can make it easier. But I'm not aware of any such bot or tool.

In short, the best solution is to just remember to log in &mdash; every time you go to make an edit or post, stop to ask yourself if you're logged in. If you're not sure, go login. i tried renaming... shouldn't that work?
