Here is a link to the Mormon site:
http://www.familysearch.org/eng/default.asp

They also have a new beta site that is helpful:
http://pilot.familysearch.org/

This site is helpful for their forums which you can sort by state, county, etc.
http://genforum.genealogy.com/

And finally, this site is great for scans of actual documents from the Civil War, Revolutionary War, etc. They are a subscription site but they often have free access to groups of documents for a couple of weeks at a time.
