TurboCASH is Free to download use and distribute. This does not mean that you can ask another community member to give you a demo, invite yourself round to his place to install it for you, fix all your teething problems, give you lunch and offer to let you crash on the couch for a few weeks until you get back on your feet.
Unlike a proprietary project, there is no central call centre where you can phone up and bark for service.
Free downloads and commercial plugins are sold without support. That means if you want a human being to walk you though any aspect of TurboCASH, generally you are going to have to pay them for it. This is rather like you would want to be paid if you help a customer.
With that in mind feel free to interact with other members of the community
