PokerTracker

When I spot a fish with TableTracker and try join to his table then I find that there is already ten players in the waiting list.
Can someone guide me how can I spot a fish and join to his table without getting on long waiting list?
Thank you,

TableTracker doesn't have the wait list info so if the tables are full you can't tell whether there are players waiting. You could filter out full tables by setting the maximum number of players at tables returned by the search; to do that click the Configure button in the bottom left.
