Hi i am just wondering if this is possible, thanks!
No, you can only change your full name in your profile, not your mention name (like @luke)
If you go to your user settings you can change your name and profile. If you can’t find or don’t have access to it send me a dm with what you want it changed to and I’ll do it for you
I also want to change my name
You don’t like Castform anymore? 
I do, I just want a change
Thanks @Thorend
Then probably you’ll make it iLoveCastform? 
LOL, I might change it to something tough like Monster Truck Mayhem (I actually dunno yet)
How about blending the themes - something like Monster Truck Castform?
