Sit & Go Registration Improvements
A common problem that occurred on PokerStars in 2008 was that you would try to enter a tournament that had a maximum number of entrants (for example, a Sit & Go with a maximum of 9 players), but by the time you had completed the registration process, the tournament had filled up and started, so your registration failed. This was very frustrating for customers who were interested in tournaments that filled very quickly, such as low-stakes or play money STTs.
To counter this problem, I designed a feature whereby the player was offered the opportunity to register in the next available identical event if the tournament had filled up by the time they completed their registration. This allowed the customer to register for a game on the first attempt every time, a huge improvement to usability.
