Just my couple of quid, but on the face of it, I don't think it's a bad idea from someone who thinks so rarely
Impo questions do crop up fairly frequently and something like a sticky at the top of the forum might be all that's needed. Members post their links and tips in that, and questions asked below it if there were any need.
I can't imagine there would be much discussion except perhaps pros and cons but it's all about the most efficient use of stock/substrate. Impos have worked the same in principal for as long as there has been printing.
It would become a resource for members and visitors alike.
