I guess I shouldn't write this here since BBs never write in the Help forum
Let's clear this up once and for all:
1. staff levels don't have sublevels
2. potential levels DO have sublevels
If you guys have a straightforward question like this that is basis for a long debate, feel free to BB-mail me and you'll get your answer. I do apologize for not reading the Help forum consistently, but I'm just one guy and I'd rather spend my time coding than reading the forums, so I hope you understand.
One note though; some things aren't supposed to be known. In this case, that's not the case, but I just wanted to emphasize that.
