http://www.livejournal.com/support/help.bml?mode=liveto the support area, so people can sit at the page and have it reload when a new support item comes in. Just like friends live.
Should save on people getting emails if they don't want them but still want to help support (like me).
Save server power by not having people reload the entire support page every minute, but just the checker page.
Suggestions for implementation
Not sure, but the code must exist for the
friends?mode=livepage. Not sure if it can be transferred to the help.bml page though.
