Do you think opensats would sponsor somebody to build it?

I think I laid out a reasonable rough vision on the ML.

* NIP-32 labels to post to a given group, and moderate entries in it
* user selected moderator list
* a markdown kind (might already exist, I haven't been keeping up) for discussion content
* POW to overcome potential visibility issues
* Archive client that looks like mailman archives

Eventually it would need email integration via some kind of self-hostable bridge
