The 1940 Census was released a few days ago. Very exciting news for genealogists all over the world.
I volunteer at https://www.familysearch.org/ as a indexer whenever I get a chance. It is easy to do; just transcribe documents. The Family Search site is free to use for everybody. I have used them in the past to research my family tree.
They could always use indexers so if you have time to spare and slight interest in genealogy this could be a perfect opportunity for you.
