Hey and welcome @BuschiBuschmann!
I think you win the “most complete profile”-award! I think you can look at your profile by clicking on your avatar e.g. here in this post. In case it doesn’t work, here is how your profile currently looks like:
HiHi THX for “award” 
BUT what i was missing was the part to look my uploaded background for the “Card”…
