I use this daily for 'Brain Exercise'. I began with this site in 2011 and ended in '12. Since then, they have "grown up" and surpassed my highest expectations.

The claims Lumosity make are definitely questionable. See for instance this study (http://myweb.fsu.edu/vshute/pdf/portal1.pdf) which shows that Lumosity games don't improve any cognitive skills, while playing Portal 2 does. Even if Lumosity games do help a little relative to doing nothing, there's no evidence they're better than any other random games that don't have the large subscription fees that Lumosity does.

I never signed up, but was sent a Welcome email. My email address is not the kind of email address you might guess or stumble across.
