Thanks Jie,
It's a good proposal. I think google will need a document (ODF or PDF) to register your paper. I recommend you to prepare a file.

Jie,
I open a new folder in KDE wiki about GoSC 2011. http://techbase.kde.org/Projects/Digikam/GSOC2011 It will be great if you can create a sub-page with your proposal contents Best Gilles Caulier 2011/3/29 Gilles Caulier <[hidden email]>: > Thanks Jie, > > It's a good proposal. > > I think google will need a document (ODF or PDF) to register your > paper.

Jie,
In your previous mail, you talking to be interrested by Camera GUI Revamp project, not Clone Tool for Image Editor... Right ?
