Credit, or lack thereof.

[ErnieBalogna]

Aside from the two daily offers, the only offers I have left as far as the free ones go are ones that I've already done and haven't gotten credit for.  I've searched my email for any confirmation links in case I haven't clicked them already, but I have.  I've clicked on a few of the offers again to make sure I had done them and they always say "welcome back".  How long does it take to get credited for some of these 'instant credit' offers?

Thanks in advance for your help.
