someone wanted to know why there was no place to post a reply. I don't know.
There is. It's the "x Comments" link just under your post titles on the home page. Right now, that link isn't working correctly because it doesn't take the user to the bottom of the single post page. Whether that's a fault in the theme or is because you've opted to only allow comments from your registered subscribers, I couldn't say for sure.
I'd argue it's the former. The "x Comments" link should take the user to the correct place on the single post page irrespective of whether they need to be logged in to comment or not. It might be worth looking at comments.php and seeing if it includes an id="respond" If it doesn't, add it to the <h4>:
<h4 id="respond">Leave a reply</h4>
the stuff on the right is floating in a strange way
Can be you be a little more specific? if you mean the grey lines, try editing style.css and changing:
.col {
background:transparent url(images/post.gif) repeat-x left bottom;
margin:0;
padding:20px 0;
}
to
.col {
margin:0;
padding:20px 0;
}
Under my post is some entry about tools, and I don't know how it got there.
On the Home page, it's a link to the Admin login but on other pages (eg a single post page) it acts as a navigation link from 1 post to the next. You seem to have a post (id 14) called "Below the Surface › Tools — WordPress"
Can I delete it?
Yes but you'd lose the navigation link if you removed it completely. As I don't know the theme, I can't offer any advice on partial removal. I'm not even sure which template file is generating it.
