I thought this was obvious but I add this to Mopolauta rules.
You are not allowed to use and paste here http://vk0.dk/vkprivupload ULRs. The stuff are online only for an hour and that's way too short time for discussion board.
Upload your replays / levels etc to your own server or use some other upload site which allowes to store the files for longer time, for example
All necessary mopolauta related announcements here.
