Okay, well i added square-1 to the registration now, as someone is going to come just to compete in it (can you guess who?). So in order to accommodate, i made it official. If you have registered already, you can click on the edit link in the auto email you received to add this event to your registration. I encourage you to do so as it helps with the organization process.
I suppose i should point out that we are still weeks away and we are now up to 25 competitors, so it is possible we get more people register closer to the date. So i will echo what Bryan said above. Please don't enter an event for which you don't know how to solve, or will take an exceptionally long time to complete compared to the rest of the competitors (of course, 6x6 and 7x7 will naturally take longer for everyone but Kris and Ibrahim). We want to get through all 10 events and not be rushed, but if people are wasting time at the timer stations, we will have difficulty achieving that goal.
We will definitely have cut off times now.
