Thanks, yes I'm looking at the list...general trackers and TV tracker is where I've seen some of these so far.

Some of the big tennis events make it on the general & TV trackers. For curling yes, very rare...only stuff I've seen posted was during the Winter Olympics.

I've never been a member of a sports tracker though, so I thought there is some possibility, at least for more tennis. Certainly on the t3nnis.tv...
