Display Category Entries in Reverse Order?

Hello All!

I would like to display the results on my category page from old to new. Currently it displays posts from new to old. Here is the category page:

https://www.sopranos.foochuck.com/category/episode-guide/season-1/

I’m curious as to whether this will effect the entries on my main page, which I do want to continue to display from new to old:

https://www.sopranos.foochuck.com/

FYI I’m using a modified version of the Elegant Grunge theme.

Any help on this would be appreciated.

Thanks!
