Pine.blog aims to make writing on the Web easier. Part of that mission involves letting writers make a living from their work.
If you use a crowdfunding site, or other site that lets your readers support your work, you can add a link to your page on that site in your Pine.blog account settings.
A link to that page will appear on your blog in both the header, as shown below, and the footer, as well as in the Pine.blog app. Other sites will also be able to show a link to your payment page.
Important: Pine.blog does not handle or process your payments in any way, it just displays a link to an external payments site to let your readers know how to support your work.
