Do moderators have ability to nest comments ?
I am asking because some people answer questions by leaving a comment instead of directly replying to someones question. This could get troublesome down the line because of the up/down vote system which can make a mess if the comments are not properly nested.
How do other forums deal with this?
Should there be some kind of warning message, in addition to this one: "Please do not report mistakes here and read the comments below before posting" ?
