Wordpress blogs are nofollow by default and hard to change to follow without a plugin or some coding knowledge. If you're unsure, send me a PM and I'll check your site. Jane
No it's not, you cannot code it in the header because it's basically another attribute to the <A> tag, all you have to do to make a link to no follow is to add rel="nofollow" to the tag. In firefox you can select the link and right click view selection source, that will give you the source for that link. If there is rel="nofollow" or rel="nofollow external" then your blog is no follow.
