Congratulations for the great you have done in uploading some of the MIR physics and Engineering series which are invaluable to any serious reader. Great Job! Would please explain how to insert the password “mirtitles” in order to download those WinRAR compressed MIR titles I am interested? By the way, I have some MIR books in PDF format ( translated into Spanish) that I would like to share with you and your loggers if you are interested. Please guide me as to how I can do that.
