Hello Claire,
> I would like to become a contributor to your organization. How do I > become a contributor? FreeType is a library to render glyphs of a font, written in the C programming language. Becoming a 'contributor' essentially means that you have experience with handling such a library, doing some programming work. You might have a look at https://freetype.org/gsoc.html that lists some idea – if you have more suggestions, please write to the 'freetype-devel' mailing list. Werner
