You don't need to get to get registered to comment on a Livejournal, dear. You can comment as an annoymous poster, unless the particular LJ is friends locked, which mine isn't. You can create a free account if you want though, and it's easy.
Here's the LJ homepage if you wanna find out more. If not, just follow the link I've posted in my earlier entry and leave a comment on my LJ.
