Forum:"Last active admin" function

Hi, I was wondering if it is possible to create a script which could add the name of the last admin to make an edit, and how long ago it was, to the top of the RC feed/side of the WikiActivity (similar to the welcome bot which signs with the last admin). For those who are unable to join Chat/IRC, this could help them find help quickly. --Eltomo85Talk 10:12, November 27, 2011 (UTC)
