Subject: copyrights
Dear users of this forum:
make sure you have the right to publish if you scan something and put it on this forum or somewhere else on the internet. Pages from books or articles from journals and newspapers generally can not be used, only if you have the written permission from the owner of the copyright.
There may be cases where a problem is less probabel (old technical info sheets, technical drawings) but only because it is now unlclear who owns the rights.
You can link to something already on the internet
And of course you can use all you created yourself (text, drawings, pictures)
In any case you publish at your own risk. I will and can not check for copyrights of your posts, I assume you did that. I will add this point to Forum Rules
Regards
Peter
