From my experience using Github or Gitlab is much easy and a single tool to submit patches to a project.

>> Personnaly I've put a lot of efforts to fix simple comments, be sure that I wrote "v2" here, sign-off there, cc-ed the right person, not mess my dozen format-patch versions, changed only the cover letter, ... Quite afraid of bothering that big mailing list for nothing (though It's true people have gently helped). It would be much easier with a git push, a fast online review of the diff, as on github/gitlab, and done. Also, github allows online edits, and therefore allows "elders" to do small fixes directly in the "patch". Some fixes are not worth the discussion and the chain of mails. That's what I'm missing the most personnaly. Doable from patchwork too I guess.

+1, lets not keep patching our current process or adding yet another tool.

We are a fairly small project compared to Linux Kernel and we are not developing code for the Linux kernel. Some of the process like coding standard is great, but the rest is just legacy IMO and not required to get the job done. Having tools to keep track of the minutia should free up more of your time for the real development.
