[Mailman-Users] creating a jump to various topics - possible?

[Jewel]

A subscriber emailed me asking if the information in a listserv can be 
organized to be able to jump to the various topics so one doesn't have 
to scroll down.    I personally can't think of how this could be done 
but wanted to run it by the experts.  Also, is there a setting in 
Mailman which will eliminate the redundant messages each time someone 
responds?

Thanks,
