I found a theme. I found a tutorial on how to upload my theme. I extracted the files correctly. I downloaded Filezilla. I saw her type in a host, username and password. Then started scratching my head.
I just want to use a nicer theme that fits me better. Do I have to host my blog in order to do this? If so where do I go next so that I have a host, username and password to type into to on Filezilla. If you can point me in the direction of another detailed tutorial that would be nice.
