I think there must be an option when making new table or, especially, tournament to activate some minimal delay before the next bid is displayed even if one did bid faster. After jump calls the minimal delay must be larger and message should be displayed to all players that the bid is displayed with delay by the system. It will reduce illegal (unintentionl or intentional) exchange of information - bet all of us have suffered after e.g. opening preemptively and getting doubled by RHO only because LHO did not pass immediately, but after a well displayed hesitation. It will also teach novice to try to maintain same tempo when bidding/playing not only online. Note that setting kind of maximal delay does not seem necessary - too long pauses are usually due to connection problems, doorbells etc. Although I have not seen similar feature on other bridge sites (yes, BBO lacks some that others have), still I believe it makes sense, eh?
