Thanks for your detail reply!
I do see some of the reasons, but since I am not in the business of selling scripts, and don�t have the time nor interest of analyzing the positive and negative affect it would have on the amount of sales increase or decrease it would have, it would be a total waist of my time.
At this time I have tested a few scripts and have no interest in it.
I am about to start testing a new one that look very promising but also missing a category payment as this one does (witch I like) and also your mod (witch I like also) but is loaded with tons of stuff and is free to use as long as you don�t charge money. (witch makes no difference to me as I will be charging.)
My main concern at this point is the ability to make the site look the way I want and be able to test payment and such to make sure I am not going to expose something to my customers that will degrade my image.
The pay and refund is just too much of a headache since in this instance there are so many scripts to choose from that can be tested.
While my spending time here does show some interest it is not to that extend.
However, I am interested in your mod, and if no arrangements can be made here I would still be interested in applying it to some other script. I have not looked into it very deeply but I really like the idea.
