I have enjoyed dropbox for years. I have encourage many people to join. In the past when they joined I would get an additional 0.5 GB of memory. Recenly however that has NOT happened. The last two people who said they signed up only to 2 GB of memory/NOT the extra 0.5 GB as promised. In both of these cases I NEVER got any additional GB for inviting them. I understand there is a limit on how many I can invite but I know I below that threshold. Until this is resolved I am NOT going to encourage anyone to sign up for dropbox. Thank you for your attention.
