And Bitvora HAVEN from nostr:nprofile1qyw8wumn8ghj7un9d3shjtnzd96xxmmfdecxzunt9e3k7mf0qy2hwumn8ghj7un9d3shjtn4w3ux7tn0dejj7qpqutx00neqgqln72j22kej3ux7803c2k986henvvha4thuwfkper4sau8ykj (most thecnical option maybe? but seam very well documented and seam lots of people are using it, it has a blossom integrated already)

Will be interested to know if the Haven option, can be configure as a paid relay too, to create niche communities. E.g Woodworking chat room,etc.

If more people send stuff will published here.
