By Judith Silverstein, Michael Lasky. In addition to displaying a screen name, many online-dating sites allow you to display a phrase, called a tagline. Some sites, such as Match. That option can be a bit overwhelming, though, so go with a relatively short name and focus your creative juices on the tagline. If you try to be too creative with both, they tend to conflict and create a confused message. Do a search on your site to see which is more prominent — taglines or screen names. Focus on refining whichever one is more visible.
