Difference(s) between the versions

I'm getting near to purchasing ASPPlayground, but I have a few questions that I haven't been able to straighten out in my mind:
 
First, regarding an "unbranded" version: does that mean that NOTHING about ASPPlayground appears at the bottom, or does it mean that just the copyright appears.  If the copyright appers at the bottom of the unbranded version, what more appears in the normal full version ... "powered by ASPPlayground" maybe, or something like that?
 
Second, is the "commercial version" the same as the "full version", meaning that the "unbranded version" is the only other choice?  In the purchase page it seems like there are only two versions available, but more than two names are used in various places to describe them.
 
Appreciate it,

Hi Jeff,

1. for the unbranded version, you will see no mentioning about our company AT ALL (no copyright notice). The normal version = copyright display
2. yes, the commercial version = normal version, and the unbranded is the only other version we offer. Full version is used when we make a comparison with the "upgrade" version which applies to users who already own version 2 of our software.
