For example SEO CM has an option to cache the original scraped articles and then produce whatever combinations you like(spinned, translated etc..). This is a great thing as once you have scraped the necessary content, you can play with generating the content in whatever way you want. You can delete the content if not satisfied, change a few settings and generate new one in seconds with the cached downloaded content which is kept in its originally downloaded form.@Sven
can you tell me if this is a feature that I'm missing or do you plan to add it?
