So how can you help? Very easily! When your visit FamilySearch's website, at the top you'll see a link that says "Indexing". Ignore the drop down menu and simply click on Indexing which will lead you to their indexing page. They have easy to follow tutorials, software, and projects where you can help.
One of the biggest complaints is that you can't find your family members since the name were index correctly. This is due to those who don't speak the language nor can they read it or recognize the name by simply glimpsing at it so they provide the best information that they can. Currently there are projects to index for both Puerto Rico and Dominican Republic. There are also many for Mexico, Central and South American countries as well as in Spain. Doing your part makes it easier to research and also gives back an incentive to FamilySearch to pursue those regions in getting more records digitized. The more interest, the more likely the records will be digitized. So please do your part. It's very easy and I've done plenty myself. They also have plenty of friendly people to walk you through the process or any issues you may encounter.
