Dear nGrinder developers.
You already know about this... We moved download site to sourceforge.net from github.
According to https://github.com/blog/1302-goodbye-uploads, github do not provide the download feature anymore.
I've checked several options but SourceForge is only accessible way from China and Global.
I've added Mavlarn as a admin of our sourceforge project. Please use SourceForge for final package distribution.
