If all you want to do is redirect a wordpress blog to a new domain, then it really is a simple task of creating a .htaccess file using notepad and uploading it to the root of your server.

Simple though it is, I spent almost the entire day yesterday trying to find the right solution.  It was clear from the articles I read that using a 301 (permanent redirect) rather than a 302 (temporary redirect) was the way to go if I wanted to maintain both traffic from the old blog to the new blog and, to maintain the incoming links.  SEO wise, you just need to know though that using a 301 redirect is the way to go.
