I've recently changed my username in WhatPulse from "JaumeBG :)" to "JaumeBG" and I'd just like to let you guys know how to do that if you don't like your WhatPulse username.
1. Go to WhatPulse.
2. Go to My WhatPulse.
3. Click Change your username.
5. Type in the "New username" box what you want your new username to be.
6. The website will ask if you are sure you want to change your username from what it previously was to your new username.
7. The website will say that you have a new username.
8. Go to your profile to check if it has worked and your username appears.
I hope this has helped you if you wanted to change your WhatPulse username!
