Comments:Blogger vs. Haloscan

I would like to switch back to Blogger comments, but have not been successful due my total ignorance of html. If you have been trying to leave comments but have been unable to do so, please let me know: jpalmer at uwo dot ca. Thanks.

Also, if you're an html wizard and you know the Blogger software well, I'd appreciate suggestions. I have tried the suggestion on the Blogger help page, but to no avail.
