When I go on meta chat, I am logged in as another SE user named "Jeff Atwood" I created a long time ago, which is dead now. I am unable to find a link to the "Jeff Atwood" named user through search, sorry. SO and other chats work fine (I am logged in the correct user) and so does meta.
I though maybe it was something to do with cookies/cache, so I opened a new icognito window in Chrome(ium actually) and logged in with my SE account and the problem persisted.
the ghost of the account is coming back to haunt me
Update: in another browser (Rekonq), everything was working normally, except that the name on the top was "Jeff Atwood". But when I joined a room, I was able to enter and my name and image were displayed. When I cleared the cache of the browser and again loaded meta.chat.SO, it showed my name. I guess this is a cache issue.
