While on maternity leave, I was able to dedicate time to studying this issue. I registered on what seems like all existing earning websites. It didn't take long to figure out which sites are truly useful and which ones aren't worth the effort. Of course, I would earn much more at a real job, but this is about additional income. CashBox is one of those websites where it's convenient to work and there are no unnecessary hassles. I learned about the site on one of the forums dedicated to making money online.
