I just noticed a new problem with imechanica: when a blog entry has received too many comments, additional comments will be placed on a second page but not linked properly. For example, the comment, "Work-free isochoric deformation", has a link http://imechanica.org/node/5014#comment-10406 , which leads to the original blog entry rather than the comment. One can find the comment either by scrolling all the way down to the bottom of the page and then clicking "Next" or by a direct link, http://imechanica.org/node/5014?page=1. This seems to be a rare situation that the software does not handle properly.
