I set up an email autoresponder so that when someone filled out the priority access application, they would recieve a personal email from me asking what they were looking to achieve through the program and blah, blah, blah.
I did it guessing that the ones who were really keen to sign up would respond and the ones who just wanted to get on the list for shits and giggles would ignore the email.
When someone did respond, I'd let them know that I just had someone put their place on hold so I had one place to spare. And they could have it if they wanted or they could wait another 5 weeks to get in.
About 50% of guys who signed up took the place.
This.
Very nice work, sounds like its working out nicely for you mate. Your conversion rates are decent.
