Installing a Plug-In

Tagged:  

Hi. Thanks for the great tool. I'm totally new to PP. I don't like default editor. I like to install a WYSIWYG Editor in my text editing field. I search through the forum and found many are discussing about it. I even found some plugiin files too. But i don't know how to install it.

I want to know

1. Does the PP support Plug-in or not?
2. Does it has some different name for it?
3. If possible how can i install it (Please provide the steps)?

Please reply me a detailed answer.. and once again i'm totally newby to PP and have little knowledge in PHP coding.
