It may be interesting to know a little more about one’s opponents, and more generally the other players of the site. Do not hesitate to fill out your information page. Some information like: How long have you been playing chess? Have you ever played in a club? If yes, which? In which city do you live? What are your favorite game speeds? etc., can be useful.
From the site, click on your username at the top right, then on "My account" and then on "My profile". In the same manner, it is always nice to see an “avatar” rather than having nothing in that space.
