Here's my new forum about Stoic philosophy I just created after 2 days of hard work, but the experience was rewarding: https://thestoicforum.com/

I also want to thank the wpforo team for offering such a complete plugin for free. I will definitely purchase add-ons once the website get some decent traffic. 

Special thanks to @wendell who was my source of inspiration, as I tried to reverse engineer what he has done so greatly on his own forum. 

If you have any tips and advices on how to promote a new forum, I would listen gladly to them.
