Astian Cloud 25 GB Gratis / Donationware
If the title confuses you, don't worry. The deal is simple
Folks from the Midori web browser project have an offer for Astian Cloud- (Nextcloud) - 25 GB free. First 200 registrants get 50 GB i.e. 2x storage.
You can read about the offer and find the link here:
a. Service is free, but donations by the Midori project appreciated ! Therefore I used the term 'donationware' in the title.
b. Collabora, Video conferencing included.
c. Like in previous cases, I am posting the link to the blog post from where you can find the registration link.
