I'm a poetry learner looking for a platform that allows me to share my work securely with a small group for feedback while preventing plagiarism. Specifically, I need a platform that:
Allows controlled access (so only selected people can view my work).
Provides tools to prove authorship and deter plagiarism.
Encourages poetry discussions and feedback.
I have considered Google Docs (restricted sharing), YourQuote (watermarks), and Scribophile (feedback system with limited public access). Based on these requirements, which platform would be the best fit? Are there any additional security measures I should take?
