I've seen a few answers in the First Posts queue that really should be comments. When I see these I flag the posts as not an answer, so that a mod can convert it to a comment.
I would also like to inform the poster that this should be a comment not an answer. However, in many First Post scenarios, the poster does not have enough rep to post comments.
What's the best way to handle this? Does having the rep comment requirement lead to more bad answers?
Part of the reason I am concerned about posting a comment is that it feels cold to do to a user with low rep. Having just finished the "Summer of Love", I want to be welcoming to new users. However, this feels like I am telling the new user to shut up until they get more reputation.
