I may be speaking for myself here, but u have no reason to be sorry for wasting our time; i waste people's time everyday and don't say sorry. Seriously though, u have just made use of the time we already were wasting. I was just sitting on my butt like all wheelchair people do, watching this thread, coming up with ideas for my offroad powerchair. You didn't waste anyone's time; u gave them the time of their lives. Don't give up and don't give out your ideas!
