The Make-A-List button in HubMed now submits lists to biologging, a community website for biomedical researchers. biologging is powered by Drupal, so includes user weblogs with news feeds, ratings and recommendations and much more. Here's a list I made earlier, which is trackbacked to all the included articles.
If anyone knows how to add permalinks to a Drupal template, I'd be very grateful for your advice.
