Yeargrounds is a firefox extension that simplifies searching Newgrounds content with period of one year.
How to use it: 1) Install the extension. 2) Open any content list at Newgrounds (i.e. games, movies, art e.t.c) 3) Select "Custom" range (first select in the filters). 4) Select year you want in "Year" select (second select in the filters).
Why? I did if for my self just for fun. If you want to use it - go ahead. If you don't - don't use it. Simple as that.
