@bentael Thanks for getting back to me and for all your help. In the end, Nifty took over my access to DigitalOcean and managed to set up Nodebb with my Mybb import.
It didn't work out the way he wanted, he had to dump on my droplet, the install he had worked out on his own computer with the import already included.
His guess was that my droplet was fighting the import since I had chosen the 512mo ram plan.
@marcos For a sitewide change, go to your Admin Control Panel, then go into Languages, select from there. If you want to change the language on a per user basis, then click your profile picture in the top right, then your username, then in the top right you will see Settings, scroll to the bottom, and you can pick there instead.
If the language you want is not in the app, have a look at Transifex, where you can help translate if your chosen language isn't available.
I did Restart of my Nodebb Forum and now don't work the Panel of Admin.
I have this Plugins : http://i.gyazo.com/1b437a3267beaf5db0385e572cd6239c.png

Yes, indeed, if you're looking to scale up to handle high concurrent user loads, scaling out horizontally is your best bet. We've got a client right now serving 700+ connections at the moment, and they're on four separate NodeBB instances. It's probably too much for what they need, but it's always nice to have more capacity than needed in case of spikes, etc.
