So awhile back, many of you mentioned you used lightroom for editing pics: http://boards.hellobee.com/topic/do-you-edit-all-of-your-pictures

I finally got a copy and would love any advice, tips and tricks. I have basic photoshop skills, limited to removing pimples, double chins and arm fat.

Several people mentioned downloading presets. Where are some good places to find them?

I have a Nikon p&s and cant spring for an SLR so I want to make the pictures as good as possible.

Any tips and tricks much appreciated.
