It was not clear for me too, but here’s the rundown.

1.You have to ask Nevin (nevin@cplusplusguy.com) for a number.

2.Then you send the paper to him correctly filled in with the number.

3.Then you wait.

Br,

Subject: [isocpp-sg16] About new proposal for adding formatter for fpos

Hi,

I'm Liang Jiaming. Recently I've floated my idea in std-proposal mailing list for adding formatter for fpos (see ISOCPP std-proposals List: [std-proposals] Adding formatter for std::fpos), the type typically returned by `tellg/p` of C++ streams. After multiple rounds of discussions with Authur O'Dwyer and Victor Zverorich, I've finished my proposal design and wording (see ISOCPP std-proposals List: Re: [std-proposals] P3070 and formatter<fpos>, was Re: Proposal draft for adding formatter for fpos). The proposal draft is uploaded to PXXXXR0: Adding formatter for fpos (extra-creativity.github.io).

This is the first time I draft a proposal, so I'm not quite familiar with the related procedures even after reading How To Submit a Proposal : Standard C++ (isocpp.org). It seems that before presenting the proposal to LEWG, I need to present it first to SG16 and the paper needs to be assigned with an official proposal number. But I'm not quite sure what I should really do next, so I send a mail to SG16 mailing list. Any help would be appreciated :-)

Thank you all in advance!

Liang Jiaming
