@agateau Thanks. No problem and I just added a little '[1]' update: I got news from my instance, Framapiaf isn't removing automatically the comments after 30 days. I assumed it was like that because of a bias: 30 days ago they flushed accidentally it during an upgrade. it's not planned for it to happen again in the future.
So, maybe adding a masto ID in my admin panel and writing a link in the footer to invite to read comments is probably something I'll do.
@davidrevoy @agateau If you plan to do that, here is the helpful link :) https://carlschwan.eu/2020/12/29/adding-comments-to-your-static-blog-with-mastodon/
