How do I delete my progress on a dedicated server?

So, I joined the server of a friend a few days ago. For unimportant reasons, I want to reset my progress on the server and start from scratch. Is there an option for me as a non-admin to to that or does my friend need to do that for me?

I think you are confusing this site, the forums of Grav the CMS, with GRAV the First Perrson Shooter.

whoops, that could be^^
