Help adding plugin to Calibre

[Jodievt]

Hi guys,

I have recently bought a Nook, and have well over 600 ebooks in lit format and PRC (mainly) and would like to figure out who to add a plugin into calibre - I downloaded the mobidedrm.py - gave it the extension mobidedrm_plugin.py - zipped it and now have no idea what to do next.

Im not familiar with python but would like to know something that has a user interface so I can rip DRMs off all my ebooks (I have the python scrips for all formats so far... I think) so I have the luxury of reading on my nook, on my iphone and computer if I so wish it.

Thanks

Note: I may come back further with some really dumb questions.
