Melisende of Jerusalem (my particular favorite; though I wrote the article before I knew how to write in text citations in Wiki and need to go back and add that)
Though I didn't have an account then, I completely rewrote the history of Naboo, from edits under 67.717.180.209, 205.143.204.110, 205.143.204.110, and the major rewrite of 205.143.204.198, and Corellia under 200.158.192.187.

I did start an account under Wildorchid, and Drachenfire, but have long since lost those access codes and only used them rarely even then... and haven't yet found a way to gain them. Drachenfyre thus will suffice.
