Forum:Logo and Wikia Problems

I changed my logo for my Wiki about 2 days ago but it has not changed from the time that I have uploaded it. Another question that I had was if it was possible to change it from wikia - Lifestyle to Wikia - entertainment in the top left hand corner. Here is the link to Outsourced WIKI.

 * It's a Wikia cache issue; just wait about another day.  Manyman  (Talk)  05:33, July 10, 2010 (UTC)
 * Please w:c:outsourced:Special:Contact to report it. The function that used to update the wiki logo used to happen in minutes, not days. Also, if you do report it, please post the response from Wikia here. -- Fandyllic  (talk &middot; contr) 8:29 AM PST 10 Jul 2010

How do you add a logo
I can't figure out how to add the logo to Robotech Invasion Wiki -- ACSBehemothHellcatCruiser ACSBehemothHellcatCruiser 19:51, July 10, 2010 (UTC)
