As of today I’m officially suspending sales and support of Mint and Fever. But! As self-hosted software, absolutely nothing changes and you can continue using both Mint and Fever as you were yesterday.
I wish things had gone differently for Fever. There may not be a market for self-hosted RSS readers, but I am sure Fever would thrive as a open source project for those who like to 'roll their own.' Would Shaun be willing to set Fever free?
