Arnold - thanks for the explanation. I kinda thought there might be another version of the story. The forum certainly does not want to get embroiled in a copyright suit. I'll continue to post my photos or links as is my practice. I do not envy the staff who has to manage this stuff, tough job.
Just a note - a copyright is created when the author creates it. The author does not need to file with the government to establish a copyright - it simply exists by law because it exists. Basically everything is covered by copyright and unless you own it you are limited on how you can share. Way too much detail to go into here - as a non-attorney I have been working with copyright issues for 4 to 5 years at the university and still need to consult copyright attorneys when issues arise. Rule of thumb - if you own it you can post, if not, don't post or get written permission.
