The email@example.com mailing list is for discussing newlib, asking questions, reporting bugs. There is the newlib web archive if you'd like to browse the list discussions. If you would like to join or leave the newlib mailing list, use the form below. It is a low-volume mailing list.
GIT commit messages are automatically sent to firstname.lastname@example.org (pardon the historical name of the mailing list) so that people can see changes. Don't send messages to this list, it's automated. Feel free to browse the newlib-cvs web archive. If you would like to join or leave the newlib-cvs mailing list, use the form below. Expect less than one message a day from this list.
There is also the email@example.com mailing list for discussing embedded development with the GNU tools. You can also check out the crossgcc web archive.
