Help with Line Follower

I recently purchased a Boe-Bot and have been through all the Tutorials in "Robotics with the Boe-Bot".
My robotics club (PARTS)·has a number of line following challanges that they presented to our group.
1) The first is a straight line with a 90 degree turn.
2) The second is passing by the first intersection and taking a right at the next intersection.
3) The·third is somewhat more complex.
The robot will need to follow a line past two intersections and take the third intersection to the right.· It completes the challange by stopping inside a large black dot (6" dia).
I just purchased the Parallax·QTI Line Follower App. Module.· I am told it contains code for basic line following.
My question is: Does anyone have any experience or code written or any suggestions, hints, etc.·for using the Parallax App. Module for a challange such as #·3 above ?
Only one of our member has taken up the challange so far. He's using a custom robot, (not sure which microcontroller or coding) with a custom circular array of 10 emitter/ detector pairs (PCB's).
His stragety so far is kind of a left hand turn rule: whenever·the robot·detects·an intersection or looses the line,·it will make an left hand turn to reacquire the line.· Seems to be doing quite well with this approach.· Eventually, he plans to have it remember (store certain values in EEprom) intersections·to improve his time·completing this challange.
Thanks for any suggestions, etc. !!!
