@ELNS @kargl @FortranFan @vmagnin This thread raises an important question do discuss. I opened a thread about it here: > [@License of code posted to the Fortran Discourse](https://fortran-lang.discourse.group/t/license-of-code-posted-to-the-fortran-discourse/188): > > A recent [thread](https://fortran-lang.discourse.group/t/tan-lamberts-formula/180) raised an important question: How to license the code posted to this forum and can it be reused? It’s important that we discuss this, agree on some solution, and post it as a guide in the sticky “Welcome / Read this First” post. If you post your code to the forum, you should have the right to claim copyright on it and license it how you want. However, most people just post code and don’t worry about how it’s used. We should have some common (default) baseline on what happens to … The way it worked out in this thread is I think exactly how it should work: @ELNS asked for permission to reuse the code, @kargl responded with his terms. Later, @FortranFan posted his own code with his name in the header. I think these are good examples of how it can work. --- _[View the full topic](https://fortran-lang.discourse.group/t/tan-lamberts-formula/180)._
