Was just setting up everything for our game, people and company in the wiki.
Realized I had written my 'New Person' entry in first person instead of 3rd, so I tried to delete the entry with the "Delete This Submission" link at the top right of the 'wiki-submissions' page. (It was still in 'pending' status)
When I clicked that, it goes to a 404: Not Found page.
So there seems like there is no way for me to delete the incorrect submission, but I guess your moderators will spot it :)
