To be honest - you're now talking about a fully fleged filtering system - which would be absolutely fantastic...
A page with a set of drop down boxes - one for registered users, another for board, maybe date range, maybe wildcard filtering for subject, maybe a list of all threads that person "x" has posted in? Click "go" and you'd get a list of threads. Probably "easy" to program as well, especially for someone of Rich's calibre... And I know I'd find it usefull.
Question is - time. I'm guessing Rich's job doesn't really involve thumb twiddling!
It would probably also increase the load on the server quite a lot by throwing lots of queries at it where people start asking for all threads by joe bloggs written before Jan 1 2005 in the 3D Chat board... I dunno! Maybe it'd be ok.
