Username Function on the Site

I’ve been trying to sign in for awhile, but when trying to input my username, it says there cannot be two special characters beside eachother.
My username is YuUuUUu__RI and it’s not allowing me to put in the 2 underscores.
Can anyone help with this?

Hi @YUUUUUU_RI,
Unfortunately that’s a limitation of our forum software. It won’t affect anything other than how your name appears. Has your in-game rank been updated? If not what is your Minecraft username, and I’ll fix it for you now.
