No disrespect intended, but this is nothing but a for-profit
advertisement (a lengthy one) explaining and linking back to your own site for potential sales.
While this isn't prohibited here to my knowledge, the fact that you've posted just three times since joining PF mainly for the sole purpose promoting your site... well...
it just doesn't come across as well as more direct involvement in the forums might. To me me at least. These are just my thoughts. Cheers.
All that said, the presets are a great idea and appear well done based on the these examples and descriptions (the same copy and images also the website).
