when something seems to good to re true what do you think most people do after reading it?
Average response is to chuckle and click away thinking "whatever their game they're not sucking me in!"
To bridge the credibility game give them a reason why you are being so generous to complete strangers.
as an example: To attend this once in a lifetime conference oppportunity completely free of charge all you have to do is pre-register. It is limited so it's strictly first come first served. Register Here______
Now you will have secured someone who will definately be at your conference, plus you've gained a mailing list.
