In GroupLens, an article is rated on a scale from 1 to 5, inclusive. Where 1 means something like this article is a waste of bandwidth and 5 means that the article was really good. The basic question to ask yourself is, "on a scale from 1 to 5 would I like to see more articles like this one?"
There are four ways to enter a rating for an article in GroupLens.
The next two commands, n and , take a numerical prefix to be the score of the article you're reading.
If you want to give the current article a score of 4 and then go to the next article, just type 4 n.
Go to the first, previous, next, last section, table of contents.
