I have a prizm too so I might enter a ti program and a prizm program... is it against the rules to enter two programs or maby even three.That's an excellent question, actually. I think that it would be fine to enter in more than one, or even all, of the categories, but I think it would be good to have a rule that you could only win in one.
Edit: I should comment that your post there was much better and more constructive, and you even tried to do some capitalization, but you still have a ways to go. For example, TI and Prizm both are capitalized, and question marks (?) go at the end of questions.
