Outbreak Server Resurrection

Can any of the mods here offer some assistance?

My username here is 15 characters long. One character longer than the 14 character limit in the login screen ingame. Can I change my username on here or do I have to make a new account?

I'm not a mod, but my recommendation is to just make a new account (which I actually just did today). It's not the end of the world, but admittedly a bit inconvenient.
