I've made this quick fix, which can be set up with cron to check for new comments and notify you through e-mail.
Someone with more geeklog knowledge could probably have it create a proper url with a link to the new comments:
Text Formatted Code
<?php
require "config.php";
# this is a text file where I store the last seen number of comments
define('CNT_FILE','/path/to/geeklog/geeklog_comments');
# this is the destination e-mail for notifications
define('DESTINATION','your@email.com');
$link = mysql_pconnect($_DB_host, $_DB_user, $_DB_pass);
mysql_select_db($_DB_name,$link);
$res = mysql_query("select count(*) as cnt_comments from ".$_DB_table_prefix."comments");
$cnt = 0;
if (file_exists(CNT_FILE)) {
$cnt = file_get_contents(CNT_FILE);
}
$arr = mysql_fetch_assoc($res);
if ($cnt < $arr["cnt_comments"]) {
file_put_contents(CNT_FILE,$arr["cnt_comments"]);
$rs = mysql_query("select distinct sid from ".$_DB_table_prefix."comments where cid > ".$cnt." order by date desc");
$msg = "There are new comments in the following stories: ";
while ($arr = mysql_fetch_assoc($rs)) {
$msg .= $arr["sid"];
}
mail(DESTINATION,"new geeklog comment",$msg);
}
mysql_close($link);
