@julian happy to share what we came up following your directions and share plugins and code with the community.
Let us know if this is of interest.

@julian This should get us started.

@Yann-Kronberg @julian any feedbakc on this ?

I have a lot of engineers... so Happy to do this for the community.
It would also be a great enhancement to the product as it would allow to create block that are different from message thread.

@julian - I am happy to develop this and make it available to the community.... With a little bit of guidance. Let me know if it is of Interest to you. Nodebb has a lot of the functionality we want to use

In other words, we would have a block with multi entry and when user want to drill on this new type of block he can see something like this:

I want to keep the forum messages but instead of posting only messages I want the user to be able to post a product that he wants to build (think Product Hunt).
Essentially it would be a form rather than a simple message. In that form the user can post a video, a picture, different descriptions etc...

How do I do this ? Do I build a widget, a plugin ? or did somebody already built this for Nodebb ?
