I think that is why we were advised to make the acquaintance of FLL or FTC teams. They are familiar with programming the NXT for their respective seasons. Most of the FLL teams are done for the year, but I think FTC are still active. FLL teams are also harder to find.
There has been speculation about restrictions on programming language for the NXT. I will eventually scour the rules to find it. It's only needed after a climber minibot is built that needs an NXT.
