Solve Together

The idea was to have a platform similar to reddit, but for students to solve exams and assignments together.

In reddit a user can create a subreddit for a specific topic, and all users can participate.

Similarly, in Solve-Together you can create rooms for a specific subject (example: Physics 101), and anyone can view this room with all the posted answers and discussions, but only sign in users can post, comment, upvote/downvote.
