We have been asked how to access CVS anonymously

Each group using CVS has a link pointing to such information, which you can find at the top of the group page, in the Source Code menu.

For example, check the top of https://savannah.gnu.org/projects/emacs

The link points to https://savannah.gnu.org/cvs/?group=emacs which contains information on how to access Emacs CVS repositories.

Just replace 'emacs' in the URL with the system name of the group you are interested in, or visit the "CVS" link on that group page.

To find a group page, you can search for the group name using the search box in the Savannah menu on your left.
