This might be a bug. When a user posts using the quick reply the thread does not update in the active threads. This is aparent on my board because I link to the active threads.
For example: in this thread
http://degster.com/midi/board/t13.html
I posted last however it does not say this here:
http://degster.com/midi/board/search...&searchid=2803
(yes, I know it's linked to an individual search)
