Maybe it's something with my computer then but I still see all the old dates. Thank you for checking.
Use "F5" on your keyboard to force the refresh of the web page. If that still does not display the September 30th details, you can find the information on the BOTC Tryouts Forum.
Note that if you click on the "Find Out More" link at the bottom of the home page, you will be taken to the original (older) tryouts from earlier in the month.
