I don't mind making 5 posts (well, 4 after this!).  One thing I'm concerned about is the 4 hours browsing. 

Why? I tend to lurk, like I did here.  I've already read hours and hours before I felt the need to register to post something.  Will those hours previous
to registration count?  Probably not.

That said, no reason to complain, just meet the requirements and move on.
