an index.gmi file inside each folder

If you have created additional folders for your flounder account consider adding an index.gmi file to them. The convention is for browsers to serve a file called index.gmi if just a folder is requested. If that file does not exist and someone navigates to that folder without specifying the full URL of the gemini they will get the following error

(e.g. AV-98 error): ERROR: Not found

Here is an example folder that does not have an index.gmi folder

gemini://fedi.flounder.online/errors

It does exist however as navigating to a gemini within it will testify:

gemini://fedi.flounder.online/errors/error-testing.gmi

Your index.gmi file should probably list all geminis in that folder and optionally include links to other folders you have or geminis within them. It is up to you.

In a later gemini I will explore a rough-and-ready way to approximate an atom feed or similar for your geminispace which I have seen discussed elsewhere on gemini. The purpose of this is to allow people to subscribe to your gemini blog and so they will be informed when you make a new post and will not have to manually visit to find out this information.
