MathOverflow is a community for professional mathematicians, who connect in a Q&A forum about research-level mathematics.

It's completely free to create a MathOverflow account and start interacting with other members of the community. The forum works with a voting system. Members can vote questions and answers they find useful to prompt them to the top. Additionally, as you collaborate, you will earn badges that show your level of commitment to the platform. The most active users end up gaining moderator-level access to the platform and can edit others' posts and vote on community issues, for example.

On the other hand, it's worth noting that the forum focuses on specific, concise answers. Is a good place to post a question that has a practical, short answer. However, MathOverflow doesn't allow questions that require a super detailed, long answer or those that are open to discussion.

Overall, is a great forum to be in if you want to bounce off ideas with other professional mathematicians online. As you discuss research-level mathematics issues, you will enrich your research and be able to share your knowledge with other peers.
