Steps

1. With only 12 letters to make a username, you must pick a name carefully. Many people think having numbers in your name says your not creative enough to make an original name. Names also depend on what you will do in Runescape.
2. If you are a pure (you only train one skill, such as strength), you should have a name having something to do with your skill. An example: "Archer_Boy" would be a good name for a pure ranger.
3. If you are a main (working on all your skills) choose a name that isn't in just one category. Such as: "Mage_Dude" would not be a good name for a main because the character is not a pure mage.
4. If you are a PKer (Player Killer) then you should have a scary name. "I_PK_U" or "U_Will_Die" would be good names for a PKer. Although it was mentioned before that numbers aren't brilliant, they can be a PKer's best friend. Adding spaces and numbers to your name makes it nearly impossible for a victim to look up your stats quickly.
5. Note:If you write pker or pure then more people might look up your name before they fight. If, however, you want to trick people saying you are a range pure and in the dueling ring pick a mage fight.(Secretly you will be a mage pure and you will very likely own them.)

Tips

• Another great idea is to choose a name that has to do with something that you're a fan of. An example is if you're a fan of Naruto you can pick Naruto_fa_n2.
• Don't make a name too complicated or does not make sense. Names should be funny, cool or different, but should make sense. If you can't find a good name for you user, try choosing something like, hello936 or 14236 or hieeeee123 or goodbye765.
• Try adding on things like XxX, XOXO, XO etc. to the beginning or end of an already taken user name.
• Also if you do pick a name with numbers use it to fill in letters such as 0 for o or 3 for e.
• You can always use your nickname as your SN, adding Xs at the beginning/end.
• If you are trying to avoid being looked up quickly, try giving yourself a name that is confusing to remember and look up, like "nmnmnmnmmnmn".There is an almost endless number of combinations in confusing names that will confuse your opponent. Anything that looks the same will be great. Like o0o0o0I1lo0o0.

Warnings

• Names could make you have an appearance that you don't want people to see. Hot_Beast would make you look like an idiot.
• Remember, you can't change your name once you made it so you better like it, but you can make a new character though.
• Do not pick an offensive name. Check your name before verifying the account and make sure that the name is, in all ways, clean and appropriate. If you have an offensive name and do a website action, like setting recoveries or changing your password, they will find out quicker.
