iWeb to WordPress converts your iWeb blog to a WordPress blog.
With MobileMe being discontinued in less than a year, iWeb blogs will not be able to have commenting or a search feature.
iWeb to WordPress converts all of your iWeb blog posts and comments so that they can easily be imported into WordPress. All of your usernames, post dates and comments are retained.
*Note: iWeb blog comments are store on MobileMe servers. When MobileMe is discontinued it is likely that blog comments will no longer work and they will no longer appear on your site. This means you can potentially lose your blog posts and comments if you do not save them outside of iWeb. iWeb to WordPress makes this very simple to do.
