Can I use GitLab's Wiki feature to create a Q&A forum similar to StackOverflow or Reddit?

I am investigating a way to set up a knowledge transfer tool on a closed network for company proprietary data. I was wondering if it was possible to use GitLab’s Wiki feature to create a Q&A forum similar to StackOverflow or Reddit?

The idea is for coworkers to ask their proprietary questions on the forum and have the answers well documented. Then people could use the search feature in GitLab to find answers once we have a good amount of them saved.

I am also open to other ideas as well, but it is difficult to get new software onto the closed network, and we already have an instance of GitLab running on it.
