I hope it is the right SE to ask. There are sites like gmane.org, mark.info and markmail.org where you can browse mailing lists of various open source projects and Linux distributions. Which is pretty cool, you don't have to subscribe to all mailing lists.
What I want is to find such a site where you can browse the e-mails by subject, aka. thread view. So you don't have to click one by one on each message if you want to read about a topic.
Is there such a site offering exactly that?
