You're not starting a stink & I'm not making one either. I'm merely expressing my opinion. Please don't take my words harshly. If we were talking in person, there would be body language & tone of voice to convey intent. It does bother me that they do not declare the fee up front. I really hate it when I go to a site & they want you to fill out something & when you get to the end THEN they ask you for money. If I had known beforehand, I would have saved myself some time & grief & not filled out the form in the first place. I have learned to be wary when such is not declared free right off the bat.
It is totally your right to think it's a neat thing. If you think it's neat & you do it, then good for you & I think it's neat that you did something you considered neat. Go for it if you want to.
