Pull request protocol?

[wzph]

Hi there, and thanks for releasing the library on github.

I don't seem able to send a pull request to the github user "facebook." I've sent a couple to the user "yujuan"--is this the appropriate way to do it?

Hi, wzph

Thanks a lot for your suggestions! For the change of the SDK, we usually first do internal change with test and code review, then we can push out the change to github. I am currently merging your change on my local copy and it would take effective in a few days. Thanks a lot and please keep sending your suggestion.
