Together with @katos and @Frink I've started a new Forum for IT professionals (and people interested in IT) to hang out and talk IT and other random stuff. It's clearly still in the very early stages. However, thanks to all of the awesome extensions the community provides it's off to a great start feature wise.
Still working out the exact tag structure, site design and Logo. But all of that will come in time. As usual regular work and Flarum development come first for me.
