You should consider contributing if you have the chance! See this PR for how I've added a new question: #275

Don't worry about the companies section - that is something that is populated by a cron job that we can manually run after the questions have been added.

Happy to do that, my contribution timeline is a bit longer right now so might take a week or two. I opened the issues mostly for tracking purposes, I may add more problems as I encounter them and whoever manages to open PRs for them at various times can tick them off here.
