Admin Forum:Serious Design Issues... Help?

My wiki, tsclg.wikia.com has some issues. I am the founder of another wiki (cartoonwarssaga.wikia.com) and it is very very different. The admin abilities are easier to implement. On the dashboard there, I have a list of tasks that would help the wiki, but I don't have that on the first one.

Also, I'm trying to add a bacground image, but it's not working. The max file size is only 150 KB, which is hardly anything at all. How am I supposed to get an image that spans the width of the screen that is only 150 KB? I can't make it work, unless I make the picture really REALLY pixelated, and then it looks bad. (Obviously.)

Also, could someone take a look at the wikis and try to help me get the main page looking better? I'm pretty lost.

This really doesn't make sense to me; the big difference between the wikis. It's just so much harder to navigate the first one, but the issue with the background applies to both.

Thanks,
