The "Mentor Program" you guys got is really cool. I do however feel compelled to give you some feedback on a certain aspect of it. The little mentor square right below the buy trains square is great... when you can see your mentor's avatar in it. Unfortunately, most of the time it is blank.
Just thought I would let you know... I'm sure you know about it already... but anyway. Very cool feature, big problem.
Once it disappeared completely and I thought my mentor had dumped me. I was very happy when it reappeared.
