Please give the students a small introduction how to post code
- tell the goal of the project
- what they did / tried sofar
- what did not work
- what they expected
- what they got
- use the # button to post code (looks better)
The more they tell , the better answers they will get
Almost forgot, please tell them to spend a few hours on the tutorial and reference section of the forum, there is so much to learn there. And the playground is also a good place to learn some things.
Finally - The forum has a search function (upper right) please tell them about that function too
