Hi, welcome to Community Central! Thanks for your edit to the User:New Captain page.
Hey New Captain
Nice to see another Aussie I'm from SA.
You are not alone with a wiki that not many others help. Mine is the same. --
background photo Edit
Hi I only worked this out today
You change the background photo by using Theme Designer and changing the wordmark.
Theme Designer is under My Tools on the bottom toolbar (you have to be an admin first)--
You could ask to be made an admin or ask to adopt it. http://community.wikia.com/wiki/Community_Central:Adoption_requests and ask there. They have rules/criteria but they can grant bureaucrat rights as well.--
Following up! Edit
Hi there New Captain!
I'm just following up from when you posted in Founder & Admin Central that your wiki could use some editors. How did that work out? Where you able to get more editors? If you could just take a quick second to my out my super short survey, it would be greatly appreciated! Pretty, pretty please??
