Quoting from an announcement on the Mocavo web site:
In October 2013, we announced our Free Forever Revolution and made a commitment to launch 1,000 new databases every day. And we’ve kept that promise every single day since. There are now more than 212,000 databases on Mocavo – more than any other genealogy service – and in fact, more than 80% of what’s available on Mocavo isn’t available anywhere else.
We’ve received a ton of amazing feedback and to thank you for all the support, we want to do a couple special things for the Mocavo community.
Instead of just the 1,000 databases we’ve promised, today we’re launching more than 10,000 new databases online for free.
We’re also opening up Global Search to all of our Mocavo Basic members until midnight on Sunday!
All of our content is available for free, but to search it all at the same time using Global Search we normally ask you to upgrade to Mocavo Gold. This weekend, as another way to say “Thank You”, Global Search is available to everyone. Now is the time to find your family!
