Pilou, here is in example page, when searching for example for a base64 encoder/decoder *source code*.

Hosting binaries or .zip archives is no good idea because people would not know what the file contains, like viruses from Windows users etc.

You can see on my picture on the top left how many base64 encoders are written in what language, which people can choose to download.

Hope this helps you to change your mind about github usage!

P.S. what would be of course a good idea imho is when MoI users would upload there MoI JavaScripts to Github too, so in case their own side goes down we we would have it on Github! :-)

Regards
Stefan
