How to user usernames online? Important!?

[L]

Usernames are of coarse a big thing online. People around the world make usernames everyday for different websites. I have a question though, which is what the headline states (How to use usernames online?). I'll do the best I can to explain what I mean by that question.

Let's say "Bob" had a username called "Eggman123". Now Bob, uses that name for all of his websites and online needs. Why do people make usernames the same for everything? So Bob, enjoys his name and then signs up to a website, but his name was now taken. Then what? Just make a different name? Like make a whole different name?

All I'm saying is, what is the best thing to do when making a username online? Using different aliases or the same one for everything and hope it does not get taken on a certain website?

Many of us adore a username that we have, like myself and one day I signed up and the name I enjoyed was taken. Kappa (Kappa means Troll Face)

Someone answer back? Thank you.

Add a significant amount of rare numbers.
And, @Tirzah if you don't know why did you answer? Surely it won't be as effective.
Or try adding number and letters for a name.
For instance, Z0ml3ieHuntress. It might be common but most likely not with the numbers.
I know rarely every can you do @ in usernames, but when you can try these suggestions:
K@pp@

Might not be exact but it still should be okay. Hope this helps!
