Just a quick post here.
I noticed today that I had none of my autosaved replays saved anywhere and if they got lost I would really regret it. Maybe in ten years I wanna go back and watch them or show my kids how awesome their daddy is xD
So yeah remember to save these to an external harddrive:
C:\Users\XXXXXXX\Documents\TrackMania\Tracks\Replays\Autosaves
I hope this post wasn't totally useless
