I would like to know how many reputation points I need to perform each possible task in Stack Overflow. Is there a publicly available page on Stack Overflow from where I can get this information?
On the page itself you see a list of all the privileges you can earn and the progress of every privilege. When you click on a privilege you will see how much reputation is needed to require this privilege. Also you will get a full explanation what feautures you will gain when you get the required rep.
