Thanx for replies, wittjeff understood our concept correctly. We are going to develop software extensions and sell them later. Anyone can request if they need something and can be lucky to get it for free if we consider it could be sold later to others.
The problem is with our page design, "Development" is the heading of a very tiny column and is too long word.
My partner does not like expression "Tell us and get it for free", but we have no idea how to change it correctly :$
I just don't want our page to appear like "what Flintstone made it?"
