Thank you for sharing this great information. I do think that copyright and licensing agreements stated on Constant Content are important factors to consider when signing up with them.

Writers must really consider their content in light of future publishing and legal implications with usage rights. If you write a great short essay, and you sell it on Constant Content under Unique License and Full Rights License, you will basically sell complete rights to that essay.

So while I think that Constant Content is an enticing platform, and writers ought to take note, understanding licensing is super-important!
