This plugin will check automatically for new activities and comments and add
them to the activity stream.
The JavaScript file “refresh.js” will send every 10 seconds an ajax request to
wp-load.php to get the new activities. If there are new activities, they will be
prepend to the activity list. Comments will appear in stream mode.
While developing we noticed performance problems on our test server (very old
WAMP). So we changed the refresh rate to 60 seconds. On our new server we
haven’t those problems.
