Klaus,
I think you would get a better idea of who would sign up if everyone knew the conditions set for the demo. Here are a few things that could help someone gather an idea on if they *could* wing it;
For most demo’s, the only expense the person doing the evaluation is shipping. Will this hold true here?
How long will the user have with this system until their time expires? Typically I’ve noticed it to be no less than 1 week, but no longer than 2 weeks *unless a special event calls for extension*.
After a demo, must the person provide you with their impressions of the system? If so, public or private? Are you willing to accept any possible negative feedback?
I have time on my hands and I am always looking to try different things in this hobby, especially if costs are minimal, so that being said, I am very interested in signing up. I, and I’m sure many others would feel more at ease if we knew the rules and stipulations.
