Blog + Wiki + Forum in one

[z3br45]

I would like to create a website with a blog wiki and a forum all on the site. The forum and wiki should be accesible and editable from the frontend. I have tried around a lot with the plugins for worpress but only find solutions outdated and not working. I see you homepage, which is probably built with get-simple, contaisna forum and wiki and a blog. How did you do that and would I be abl to do the same?

Thanks in advance
