@ursalina - by chance is English not your first language? Or was your post mangled by typing on a device with auto-correction?
As I'm afraid I don't understand much of what you are asking for.
All plugins are located in the very first post of each thread. You can far more easily install directly from calibre, using Preferences -> Plugins -> Get new plugins.
Any questions about conversions you should post in the conversions subforum of the MobileRead website, as they are not related to this plugin, post some more details in your question there and am sure someone will try to help you..
