This would mean too many queries to the database, useless pressure on the server. Just use
Reload Every, if you're too lazy to refresh the page yourself. Or if you want, you can subscribe to
this forum's feed. That last option should serve pretty much what you want, if you have a desktop feed reader of some sorts, or are using Flock (feed reader built in).
As the site grows bigger, that page would refresh every half a second.
Download an autoclicker, set it to click the refresh button on your browser every X minutes.
You can normally set your browser to autorefresh.
fudge that, are you too lazy to refresh the page man?
It's not like your going to miss them. Or do you have to be the first person on every post?
If you are watching TV and you don't particularly want to get up to refresh the page, if you are using Firefox,
(it doesn't work with IE), you could get that add-on suggested by Etheryte, called Reload Every, then you can set it to reload whenever you want.
Like it's already been said, if it was really busy here, the page could be reloaded every second or so, which may be too much demand for the server, I'm not certain.
