Hello, and welcome to narrow.world. This site is part of a larger network known as Hubzilla. Clicking on that last link will bring you to the project home page, where you can find out more about it.
Registration is closed on this site, but I will open it up for people who know me in the corporeal world. Contact me if this applies to you. If this does not apply to you, please have a look at this list of public sites, or find out about running your own.
