Thank you for raising concern about each author's rights to their content posted here.
I posted this on the Refugee thread, but it may be helpful to also have this restated here:
Please be aware that the previous Terms of Service which was in place for most of the Forum's 18-year history did not provide us the right to grant permission to use or display posted content except as part of SuperTopo services. So, while you can obviously feel free to copy and paste your own content, you will need to obtain permission from each individual author if you want to use their content. Simply posting here on SuperTopo does not make content public domain. Those who post retain all patent, trademark, and copyright to any content they submit, post, or display on SuperTopo. We do not have the right to give you permission to use other people's content.
