@reva-ahlawat I would be happy to help. It looks like you made your username your first and last name. If you go into your Community account in the top right corner of the screen please click on the 3 little people icon and then select 'My Profile'. Once you are in your profile you should see a blue 'Edit' button pretty close to your profile picture. Once you have clicked that button a new screen should load. Locate and select the 'Username' tab. You can then give your profile a new username and select the green 'change username button' to save it to your profile. Let me know if you run into any other trouble! You can also PM me the username you'd like to use and I'd be happy to change it for you.
