Emre, if your beef with WPSC is because a preinstalled copy could not be removed, that is the fault of the host and not the plugin itself. I uninstalled WPSC on my site in favor of WPFC and didn't have any problems. Before you cast aspersions toward others, your plugin must be completely flawless (it's not—I'm about to submit a real bug I found).
swinggraphics, you are right. I will modify it in the evening.
