Est-ce que cela fonctionnerait pour une communauté de femmes de plus de 45 ans ?

Hi Nicole and welcome to our community!

This site, meta.discourse.org, is for people who host their communities using Discourse and help one another with configuring and maintaining their sites. We are of course welcoming to everyone but this is not a dating site.

You can use Discourse yourself to host a community. It would be perfectly well suited for a dating site! Take a look at https://discourse.org for details on how you can spin up a trial for free.
