Fencer: The comment form will only be displayed if you are already logged in. If not you have to click the "log in" link (in tvery tiny letters at the bottomof the page), log in, be sent to a weird page that seems to be an administration menu of some sort, click the "back to weblog ink", find the entry you want to comment and click the "comments" link and finally scroll down to the log in form.

With practice this takes just a few seconds, but it's boring nevertheles...
