Many people last year used the appendix incorrectly for text. The appendix does not wrap to the next line on purpose so that tables of numbers may be entered. You should check out how this looks in advance. We accept no excuses. Each team should spell check before putting the executive summary into the online system.
Teams are welcome to enter more then one submission.
However, we find that the teams that do best are those with a single entry. Only entering once allows you to concentrate in doing a great effort on a single plan, instead of an OK job on many plans.
