meta.config contains settings from NodeBB itself. Plugins retrieve their own settings via the settings module on the client side.
Import from a mailing list archive
I would like to make an experiment importing data in my NodeBB forum from a mailing list archive.
I haven't seen any specific plugin for that.
Did someone already made something like that ?
Any orientations or guidance to do that myself if there's nothing for that ?
Nothing like that exists. But mainly because it's quite a finite feature that not everyone would have a use for. If it's a one off import, look at other import plugins and amend the data to suit your structure. Repeat import would be a little more work I imagine.
Thank you @a_5mith, that's what I imagined but I think it's worth asking before putting some energy in that :).
I'll follow your advice and take a look at other import plugins.
