All dating sites require that their members create a screen name. This is the name that will be shown on all your postings next to your photo and profile. It's the name that you will be known by to all initial prospects, both members and non-members.
Some dating sites give their members the flexibility to get creative on coming up with interesting screen names, while other sites just take your name and add their own ID code to it. For example, matchmaker.com allows you to choose any name you want, provided that it's not explicit. The site will then assign a three digit number next to the name. So if you use the name "Jennifer" for example, you will probably get the screen name "Jennifer123". Granted that this is not a very creative way to establish your identity, but for a lot of people, this process takes away the pressure of having to come up with a catchy screen name.
Many dating sites here in the US allow their members to submit a short name other than a first name and include a number next to it if the name chosen has already been used, such as the case with Update.com. At match.com, members are allowed to use up to 128 characters that they can divide however they choose between a name and a tagline (a slogan or statement that describes and defines their personality). Many other sites have the same requirements for assigning a screen name.
The simplest way to establish a screen name is to use your own name, plus the assigned number that the site provides. But better yet, show some personality and try to think of a more unique and interesting name that better displays your character, personality, and / or passions. Some real examples of catchy screen names from several popular dating sites include: Qtblondbomb, Surfworld, LAreefer, Bookworm, Iluvcats, Fitgirl, Veganlover, Funindasun. These names gives the reader a clue of the member's style and personality.
Some Tips To Help You Pick A Good Screen Name
Avoid picking a screen name that is too explicit or too graphic. For example, names such as naughtykitty, Ezbrod, Hard1, etc. The site moderator will more than likely delete it or will ask you to change it. Have fun, be creative, but be responsible and use your better judgment when coming up with an interesting screen name.
Some sites retrieve the names of their members in alphabetical order. That means if your screen name is Zorro, chances are you will end up at the bottom of the list. However, if you really want to keep that screen name, you could add the letter A in front of the name (Azorro).
If you choose a dating site that does not allow you to have more than a few numbers of characters (such as a 10-20 letter limit), you have two options in selecting a screen name. You can simply pick a name of a person (whether it is your real name or not), or you can come up with something unique and creative.
If you choose a dating site that gives you more space to work with, have fun with it and try to pick one that really makes you stand out!
