Just a simple feature I want added. I want there to be the option to thank the person answering questions in contest after they answer one of mine. Just a simple thank you button. Every time I ask a question I want to thank the person who spent time to answer my question, but don't want to waste more of their time by asking another question just saying "Thank you for answering my question". Please add it if it's not too much work MikeMirzayanov or anyone else from the Codeforces team.
Thanks for reading!
