It's really a great addition. One more addition that I suggest you can implement in future that will make BBO much more exciting. I often noticed that people with limited skills in bridge claim themselves to be "expert" or "advanced". BBO can have their own ranking system, that will automatically indicate the appropriate skill level of any person playing here. Everybody should start as a "novice" and depending upon their performance in different "paid" or free tournaments and depending upon skill level of their opponents they can easily progress upward.
