I have spent many hours searching for and downloading themes and plugins for my site.
After this, I thought it would be nice if I had found a compiled collection of themes and plugins.
I compiled about 30megs of themes and plugins for you to download.
If you have a clean wordpress install you can upload the directories just as they are, but back up your theme and plugin folder just to be safe.
If you already have a collection, you and look through this collection to see if there is something you do have.
Here is the link, enjoy
