@katomm @gufmar @rdlrt what do you think of creating a C entry for language / technology (I suggested it here on the Forum)? Some of the other languages here started off with only 1 member & are doing much better today. To me it seems fashionable in crypto these days ("retro cool"?) to have C bindings and so think it would serve the community to emphasise this in the listing & pave the way for others.
