Good stuff

@baris well finally managed to get it working, I was missing to accept merging the branch when doing the pull.... but that was not enough as now it was showing me a problem with the widget essentials... so I checkout the commit for "up widget essentials" and that fixed it for me!! Thank you for your time @baris

There's no magic forum you can build and have it be popular. You'd need either a forum about something, however chances are whatever you think of will be saturated with forums already (Bitcoin for example) or something brand new that no ones done, but it won't be long before someone else does. No plugin will make your site amazing. running forums is an uphill struggle. Someone will piss you off, you'll ban them, someone else will cry about user X being banned, rinse and repeat. Starting out as a new forum now is tough. Unless you've already got a large number of members and transferring to nodebb (even then, people hate change, and you'll no doubt get the token "developer" who preaches that anything that isn't built in php is rubbish). But again, you can't please everyone.

@ogerly said: there is information about the merger of nodebb and ghost ? Not merging, but can be used with each other.

Most likely the theme will need some integration before subcategories will be shown. At present, I believe only vanilla and lavender show subcategories.
