I noticed an inconsistency on our meet opt-in/opt-out page (which is based on the short code) earlier this week and it was also seen by another team.  I suspect there is a bug that I need to track down.  In my case the report generated from the short code didn’t include all of the swimmers that the meet report generated from the Options->Reports->Swim Meets tab on the Dashboard included.  In looking at it, the Dashboard report was correct, the short code report was not.  I plan to chase this down in the next day or so.
