Poor "next in thread" functionality of public mailing lists

Hi,

In the archive of the public mailing lists at 
http://lists.w3.org/Archives/Public the "Replies" and "Next in thread" 
functionality is limited to the period in which the current message lives.

This is rather troublesome, since it becomes very difficult to review a 
conversation that took place over an extended period of time.  (On 
www-style, for instance, such conversations occur frequently.)  As a 
result, follow-ups often get missed, seemingly leading to WG decisions 
being made on the basis of incomplete information.

Would you consider changing this behaviour?

Kind regards,
Anton Prowse
