Yeah ... they had major issues. First off, the submit system was flaky (didn't work with common browser configs ... e.g. on my macbook pro with Safari). They had a 6 minute time limit, which caused a lot of problems. By the time someone realized their browser config didn't work, it was too late to try another combo. The questions were not worded precisely in some cases. And some people were cheating like crazy ... putting up their code/test cases for other people to use.
