The deadline for pre-registration has passed yesterday. 27 teams have pre-registered, so we are looking forward to a big and interesting tournament. Actually, we had hoped to get at least 28 teams, so that the IYPT2010 would be the largest IYPT (in terms of competing teams) of all times. Nevertheless, 27 is a fine number, as it is divisible by 3. If no teams cancel, we will not have exhausting fights with 4 teams.
As Tim mentioned earlier, we are still working out a few issues with our online registration system. As soon as it is available, we will send out user names and passwords to all pre-registered teams, along with some general information on the registration process.
