I don't know quite why 'professionally' that no one would share the code as Mel put it, perhaps i'm missing something?
Think about it - it would be commercial suicide to post some of the more complex code and allow competitors to bring their products to market. For you this might be a hobby, for others it puts food on the table and pays the bills. To put it bluntly, I'd rather the fruits of my labour went into my bank account rather than yours. *smiles*
