I need opinions on how to automate and make a easy way of adding many pages or subdomains to my blog. I made a portal site in a wordpress blog form its like a mall directory. I now need to make one page product pages of all my affiliate products to promote and link them to my main portal site. What is the easy and faster way of going at. I do not want to have to add several hundred sub domains for each product manually. Is there a better way of automating this. Someone mentioned wp-mu. Also how to do it in a way for SEO benefit. Thanks.
