Type Light is a font editor developed by CR8 Software Solutions and the crippleware version of the professional typeface editor, Type. Though it has its limitations, Type Light has enough features to edit an existing font or create a new one from scratch. The program is available for Linux, Macintosh, and Windows.
I found Type Light while looking for a free font editor to do a project for my work. I used to use it to modify fonts, but I now find FontForge to be superior in every respect.
