This tutorial explains how to install a commissioned journal css to your Skins. It only covers the main parts for beginners.
I did not explain how you change the urls to images used in your journal; as I expect that is something that the creator you commissioned will explain or if you're lucky already did.
So, in case you have any questions specific to your skin, please go and ask the creator for his/her assistance.
No, but where's the problem with that? I don't see one You hit the Install button and tada - the Journal is ready for you. YOu just click onthe corresponding thumb and all is done for you, except you need to write your entry.
(without giving them the codes and everything) (just for them with the 'instal button')
