Will there be ladders added too later? So not just WRs/PRs, but also the rankings per chart? 
Yes of course! I will add them soon... 1 or 2 week ;-)
EDIT: Djo, can you change my 4:40:30 Special cup submission to a 1P run? I don't think I can edit it anymore.
I change 1P and a put the real date! (you can't edit speedrun until now... sorry)
Other thing : when you put a video for a all cup you have to add for each cup also with the correct time => you add for example "&t=478s" for Flower cup. Like this you will have also video for speedrun by cup!
EDIT: and format for RT is 00'00"00! I correct also
