The twinery.org has some links to projects related to twine development but some of them are broken.
In addition there is no explanation on which projects are active.
All in all for new users of twine it is IMHO difficult to find the right projects to search/submit issues/requests or simply find information.
There is no information on any maintainer of the website either so I’m hoping this message reaches the right person(s).
I’m not sure why he wrote it that way. The intro text is probably something he forgot all about and so it hasn’t been updated.
The correct repository is this one, which is the last one he lists there for some reason. This is the one that Chris maintains and all bug reports should go there. That github also has a list on the main page with up to date links for the repositories of each story format.
