As correcting or punishment
There is a new method for correcting bandy legs.
The word for someone who is always correcting others is a critic. There are also other words that can be used like censurer, caviller or deprecator among others depending on content.
That depends on what you are correcting and how you are correcting it. If you are editing a paper for someone, then no. Just write the corrections on the paper. If you writing a conversation where a person corrects another person, you should have commas in the dialogue, but they aren't because of corrections, but because they are part of the grammar of dialogue. If someone used the wrong word, you could correct them as so: "You used the word 'depraved,' but I think you meant 'deprived.'" The comma there is necessary, not really because it is a correction, but because it is a compound sentence and you need a comma before a coordinating conjunction.
