Model class capitalization - Answer found

[eluser]cfraz[/eluser]
The user guide says that the first letter of a model class name has to be upper case, with the remaining characters lower case (except the actual file name is all lower case).

I've been looking at some good CI projects, like Bamboo Invoice, and that convention doesn't seem to be used always. I messed with case on my test models and it doesn't seem to make a difference.

Is first letter upper - remaining letters lower case for model class names just a usage convention, or will something break if I'm not careful to follow it? Or am I just missing something obvious?

Edit: Found the answer. Bottom line, I don't have to unlearn MixedCase for class names.
