Solve Together
Take a look at: solve-together.great-site.net
Disclaimer: The project was developed on (InnoDB) engine, but is uploaded on a (MyISAM) engine on a fragile free host plan just for demonstration purposes, so you will see some bugs such as when you delete a post it still appears (only on your profile).
Bottom line is: The project is better than what it looks like in the free hosting plan (It’s free so no complaints)
This was a Too ambitious project.
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 in discussions, post on the subreddit, upvote/downvote etc…
Similarly, in Solve Together you can create rooms for a specific subject (ex: 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.
The problem for me was the way of handling uploaded files, it did exactly the job, but it is not efficient for handling a large amount of files on an affordable hosting plan.
Based on my current implementation it would be too expensive to put it on a real life heavy usage, So for now, it is here only for an idea demonstration.
