Weird thing happening with my username.

I have a problem where my username and someone else's are linked. When I go to my profile it takes me to the profile of ThinkingPink(without the exclamation like mine). I think where they're so similar the system is getting confused. What can I do to fix this?

Edit to say, I don't mind changing my username but I don't know how.

PM me and I can update your name for you.

I changed yours slightly. Let me know if that helped.

Perfect, thank you!
