write.Disqordia.Space is a writeFreely blogging instance hosted alongside the disqordia.space Pleroma instance. Posts here can be federated to the fediverse if set to public, so you can repost your blog entries to your fedi friends. Registration is currently open and anyone is welcome to sign up and create their own blog, even if you don't have a Disqordia.space account (but why don't you, huh?)
Users may have up to 3 blogs. There is no cost to use this at all.
Themes for your blog are here: https://write.as/themes/
