Do you have a single username you feel attached to?
Or do you like to use different names for different occasions?
Edit two and a half days later:
Thank you all for answering my question! It was so interesting and fun to read all of your responses.
I really appreciate you for taking the time to write.
Not very. I usually make a different username per website, but they are usually a portmanteau of various characters I like. So several names I use are fairly similar.
