Add author to summary and individual post pages

We had a team of 8 people contribute to our FAQs. Our site is using the Enfold template. Since we now have quite a lot of data some challenges are coming up.

1. We would love to have the author somewhere in the summary pages. Managers are supposed to review the FAQs and if they can quickly see who did what their job is easier.

I’ve tried to scan the PHP source code where to put in author, but I am at a lost and I am not a WordPress expert. Our choices seem to be:

A. Do something built-in.
B. Fix the Enfold way of presenting data.

To give you some idea, here is our current FAQ summary page:
http://snow2.gatewaymodules.com/knowledgebase/

The above page uses the built-in FAQ summary page. Here I would like to add author to each FAQ.

The other option, doing it the “Enfold” way, is to modify the text below each article here:
http://snow2.gatewaymodules.com/faq_test/

Our designer created that page and then I found that when adding “Blog Posts” within Enfold you can specify Title + Excerpt + Read More Link. However, “Author” is missing.

The final option would be to modify a single page, e.g.:

Fix a single page post output to include the author of the post.

I guess my confusion is:

1. Should I be looking at the Q&A Focus Plus code?
2. Should I be trying to do things the enfold way?
3. Am I actually just supposed to debug WordPress pages/functions?

Any assistance (including paid for) will be appreciated.
