Vouch Copy Rules: https://www.mpgh.net/forum/showthread.php?t=816840
I respond to vouches following this format:
Quality: ?/10
Cost: ?/10 (Is your product worth the price you're asking?)
Recommend: ?/10 (Would I recommend this product?)
Time and Effort: ?/10 (How long and how easy was this method? [For eBooks only])
