For all members:
SocialAdr allows your credit balance to go slightly negative, in order to allow each bookmark that's shared to get the maximum submissions possible. So don't be too worried if you see a negative credit balance.
For Lazy members:
Every month you'll receive credits when your PayPal subscription rebills. If you're not sure what day this is, log into PayPal and take a look at your "preapproved payments". You can also contact us to find out.
For Free members:
For each bookmark that is successfully submitted to your social accounts, you receive 0.1 credits. So if you share 5 bookmarks in a day, you will generally receive 8-10 credits, assuming that you have all of the social sites setup properly. Each day that you share 5 bookmarks, you should get enough credits to have one of your own bookmarks shared.
