Wikipedia:Sign your posts on talk pages
Ìrísí
Signing your posts on talk pages and other Wikipedia discourse (but not on articles) is not only good etiquette; it also facilitates discussion by helping other users to identify the author of a particular comment, to navigate talk pages, and to address specific comments to the relevant user(s), among other things. Discussion is an important part of collaborative editing as it helps other users to understand the progress and evolution of a work.
