I just installed Gudlyf's Update Notify plugin. It does what I want it to, but there's an error in the text of the email it produces I thought I might post here for your information:
If your WP root directory is not the same as the root of your blog, the email sent out contains the wrong URL (the one for the WP root). To fix this, go to line 41 of the php file and change â€œget_settings(â€™siteurlâ€™)â€? to â€œget_settings(â€™homeâ€™)â€? .
On a different note, I ran into the internal consistency of WP (and php with CSS positioning) for the first time when I used the previous_post() and next_post() tags to create a nav bar. It was the first time I tried putting in something new (as opposed to shifting around the parts of index.php). I added the tags, arguments and CSS style and then wondered how to get the nav bar to be present only if it's a single-post page. Worrying about if statements I tried what I had done so far and 'lo and behold, if the page contains multple posts, "previous" and "next" are undefined and the navbar is automatically absent. Three cheers to WordPress!
