Someone just told me to use yEd and even said it was Free Software, but I cannot find either licence or source code, so I cannot compile it for my platform anyway.
Out of curiosity, what *are* the actual licence terms? Is it Free Software/Open Source, or Freeware (available for use without pay or much restrictions), or shareware, or nagware, or freemium (similar to freeware except there may be restrictions on use you have to pay to remove), or what?
Your website even says “yEd, which is free, …” (in the E-Touch quote), so I wonder whether that is true, or if it’s just gratis, and what other restrictions it may have.
