Go to the Profile category on your My Mibba. Click on CCS and from there will be a link where you can get a premade layout- I don't know how to make your own layout, I'm so sorry :(
I hope this helps though :)
I know what that's like, I started out here a few weeks and I was uber confused by how it all worked on this site and everything. So if you need any help figuring out anything, feel free to ask :)
