I would like to have comments enabled for a page that loops through entries of each categories and displays a summary (essentially a start page) with comments at the bottom. How can I make use of the commenting system in such cases where it is not a particular entry?
Do you need to use ee for comments? If not try disqus.
If that's not an option you'll need to create a ee entry for each category to allow commenting. One possible way to do this would be to create an entry for each category and then use custom category fields and create a cat-entry-I'd field to hold the categories entry. This
