After talking to several people, and managing to organize myself to have time ... I manage to start programming the real platform in mid-November.
v0 -> landingpage with Carrd
v1 -> Platform created with Drupal
At the end of November I publish v1 of the MVP.
It lacks many features, and you can't even pay for it. It is totally free to try to generate community.
Development time about 2 weeks (no full time). I bought an html theme to save time on the css layout.
The web for the moment is focused only for spanish speaking people. This has been to be able to publish fast and to be able to keep asking for feedback in spanish.
