. I am 90% sure I will buy the software however there are a few key tasks I require that I couldn't achieve in the demo mode myself. firstly, I wish to create two user groups one of which only has a basic profile data allowance (just an aviator and personal information) and the second to start of the same but then have 3 stages of upgrade in the form of data they can upload to their profiles. Each stage would require a different paypal payment. Can this be done ?
