Once you get access to the review queues, one of the review types is "First Posts". Here experienced users are shown new users' first posts and asked to take an action.
What should we do at this point? I've just completed my first "first post" review, and the answer was good so I upvoted. I couldn't think of anything that needed saying, so I didn't comment.
Should we just take action that is needed, or should we have a standard wording to also comment and welcome to the site (for posts where no negative action is required)?
