Several feeds in one blog

[Rachael]

Hi,

I have this blogger that has categories, each one with a different feed.

How to avoid the effect of user repetition in the sidebar ?
I can't find the syntax for config.ini in the web nor in the mailing 
list archives for this cases :(

Thank you for your patience.

I'm getting desperate with the lack of documentation of this software.

Regards,
Rachael
