btw - I also found out since,
that you CAN delete replays from the list,
only you have to do it from the save replay list.
you save a fake replay to get to your replay list,
then, you click the little x icon to delete the replay you want to remove
from the 10 replay list on your page,
since if you do it using the "delete" link on your page,
it goes 1065 on you, and it's gone.
learned THAT one all by myself, the HARD way, no thanks to wgt. :-\
