is there an API to programmatically add posts (with tags and upload an local image) with nodebb?
Not yet, but it is in the works
Development on this plugin has stalled for the moment, but it is definitely something we want done soon. I'm sorry I don't have better news for you
That might be a good plugin request: enable html for admin/above X reputation
From a category view (list of topics) you can go to tools -> merge to merge new topics into old ones.
@gotwf thanks,I didn't use 14x, I reduced my version to 12x, and then my pictures could be uploaded normally
I mention that here, too: https://community.nodebb.org/topic/13972/
What kind of changes?
