Hi Brian,
Unfortunately we would require a trial version of the Engage Events module to see how it integrates within our current system, we are looking to purchase this module with the source code but with out a proper trial version within our system we would be dubious of purchasing this module. As you have mentioned if we do just purchase the module with source code and find out the module does not do all we require we would not be allowed a refund. I understand this as we would of had the source code and then can do what ever we like with the module but is there away around that you could allow us this module to trail on our system and then for us to purchase the module and source code after we have had a trial run.
Kind regards,
