I'm trying to create a network of blogs linked to the same domain name for multiple authors. But I know very little about HTML, CSS, etc. I used to write on a blog that used wordpress.org but I find it so confusing. I'd like to buy a domain name and use wordpress.com but I'm concerned about the limited customization. I want to be able to design the pages to the best of my ability. What are your thoughts on free blog hosts (wordpress, blogger, etc.) vs. buying web space and using wordpress.org?
