I am an administrator here on meta, and also on MediaWiki.org. My administrator role on this wiki is primarily to aid with the transferral of content to MW.org, however I may (time permitting) be able to help with other administrator tasks if there is no-one else around.
Although I log in to Meta fairly regularly, I am most active on MediaWiki.org, so you might get a quicker response if you contact me there.
