I would like to announce the release of my latest site, www.InstCred.com. InstCred uses advanced technology and resources to offer postback to sites from networks that don't provide it. So if you run a survey site, GPT site, referral site, etc. and would like to use a network but didn't because they didn't offer postback, now you can with InstCred! Let me know if you have any questions or suggestions for it.
