I am quite new to this site and so far I am appreciating the help I receive . I have a question about the use of notes and I am sorry if I am asking something that is taken for granted by more experienced users. I have noticed that often notes are used to give answers, instead of using the appropriate space for answers. I assume that a note is like a comment, an observation on a question or on another answer, but not an answer in itself. But often notes are used to provide full answers with appropriate links. Is this practice correct? Does it not reduce the ability for other users, especially the less experienced, to provide full answers? Thanks for you attention.
