Placing a listing of 40k blogs onto a blog roll gives people somewhere to go and do a quick search for blogs or their topics they are interested in. There is currently a search at the bottom of the blog roll that will search all the blogs in it for your topic.
The only requirement for the blog exchange is that warhammer 40k is discussed there. Either send me an email with a link, or post a link in the comments section of a post related to the Blog Exchange. If there is interest I will be posting a weekly selection of blogs or new blogs that are on the exchange, and I am putting together a page with links to all the blog exchange sites.
If you want a spotlight for your blog, simply shoot me a quick email. Include the link, and topics you hit. A paragraph will work. Examples of topics are, painting, tactics, list building, tournaments etc.
I did not change a lot, simply the layout of the blog, which apparently takes some time. I am still currently working on the layout, and I will be refining it easier to read.
Here are the Blogs that recently listed here.
