I'm not sure which administrator or bureaucrat is responsible for the actual deed--or even whether you already took notice of the fact--but you have been granted discussion and chat moderation privileges. Congratulations!
This was not a mistake, and the promotion was at least partially motivated by my recommendation for yourself and Rumstein. Since the SL3 Spoilers page had become the focal point of this wiki's comment contributions, it became quite necessary to have moderators who frequent the page, and there are no people more suited for the job than the two of you; after all, you essentially built the page from scratch, and you also partake in the comment discussions quite frequently--definitely more often than any other moderator.
PS: If you aren't sure how to deal with something, don't hesitate to reach out to me--and I'm sure other moderators / admins would also be quite willing to help out.
