ok, I figured this out finally.
Moveable Type defaults to this, and alot of people like it.
what I did was this:
I put
<?php comments_popup_script(400, 500); ?>
in my head section of index.php
then I replaced my comments_link tag with comments_popup_link
which I think it already is in most themes.
You don’t need a comments-popup.php in your template for this to work. In fact I had to delete mine and just use the regular comments.php page from my theme, but I immagine you have to know themes well enough to create your own comments-popup.php for the display to look right.
I ended up removing mine because it didn’t look right with the theme I chose. the simple-green theme. I thought i could just copy the comments.php to comments-popup.php, but it didn’t work. Not only did the script not display correctly, but it didn’t keep me logged in either,
so I don’t know what the deal was, so I just removed it and changed it back to the old way. ??
anyway thats all there is to it.
