IMO this prefix thing isn't working well.
I like the whole idea of prefixes (especially for filtering out threads to read), however, wasn't it easier when people added prefixes in themselves?

There are already at least two threads in the wrong [Prefix].

It would appear posters either don't understand the prefix or simply don't care.
