You should be able to see them better if you open them in Flickr and zoom in on them. I'm about to post a new screencast where I go over my Breadcrumb NavXT settings. I can help you in class next week too.

Were you able to migrate your tumblr posts over to WordPress or did you have to start from scratch?

WordPress.org hosted sites are definitely better than tumblr sites, but not everyone wants to worry about hosting...and tumblr is free.

If you want feedback in class on daligatennis.com let me know.
