I think I've opened the coments up completely now, so you won't even have to register if you want to leave some kind words or snide remarks (I'm looking at you, Dad!). When click on "comments" after a post, it will pop up a little window and ask you for your identity. If you don't want to set up a permanent user ID/blogger account, just select "other". A space will appear and you can type in your name.
The only potential problem with making it so you don't have to log in to leave a comment is spam (it's not just for e-mail anymore!). I might have to change some things later if it becomes a problem, but hopefully it won't.
Oh, and about the house... they're pouring the slab today! Look for new pictures tomorrow. :)
