How the heck do you add a comment box ? And how do you create categories in blogger ? Don't tell me it can't be done...

Edit:
OK, the comment box problem has been solved, though I'm pretty sure there is a more elegant solution than linking to an off-site script. About the categories, the Blogger FAQ has this to say -

Does Blogger support categories?

No, Blogger does not have categories.

Well, thats that I suppose. I'll probably have to think of some hack solution, similar to the one used for the comments
