Audition page setup

Hello

I love to go to the audtion page to see what's coming up that I can get involved in. But lately that little scrole bar on the right hand side has been saying there's been heaps of stuff on there but really its the same posting posted three of four or five times.
I was wondering if this was due to double clicking when posting or whatever... Anyway maybe something could be done so that each message is only posted once. :)

Thanks
Hannah
