I'm not a 100% sure but I think I remember that sometimes retagging a question gave me 2 points of reputation and sometimes I didn't earn any reputation from retagging.
Can anyone confirm this behaviour or do I just remember wrong? And in case this is true, what is the explanation for it?
Once you get the "retag questions" privilege (500 rep), you no longer need to edit a question (thereby gaining 2 points) to retag a question – simply retagging gains you no points. If you have the "edit questions and answers" privilege (2000 rep), you get no points for editing questions.

When you reach 500 rep, you gain the privilege to retag questions. With less than 500 rep, you would get 2 points if a suggested retag was approved.
