Is this project still alive?


I recently discovered this site and I’m really impressed. Since the export functions for some formats are only available to sponsors, I was looking for a way to become a sponsor. The site is silent on this. In the community here I hear about problems with Lifetime Sponsorship and the URL mentioned in this context is not accessible to me either.
So, dear people, does it make sense to invest time and money here?
Thanks for your feedback.
