I'm new to this site and really like it so far. I've read all the help documents and am unclear on whether puzzles need to be original in order to be posted. All the original content on this site is extremely impressive and I think it will be a while until I can create questions as polished as the ones here (definitely something to aspire to though).
That said, I have long been a huge fan of logic puzzles and know dozens of them by heart. None of them are my own creation, but I still think the community might enjoy them.
I am wondering if it is appropriate for me to post these puzzles as long as they are not already posted on the site?
