Hahaha, you're right, the guidelines didn't mention the number of people you could invite. I guess I just imagined three there, as all good things come in threes, and so on. And as for the monetary incentives... they tend to be so low that you'd probably earn more with the post itself, underscoring your last point, that the point of a contest is really the interaction.
Anyway, I can totally see it: After being challenged, this song emerged out of the depth of my unconscious to get me to actually write this post.
Thanks again for the cool challenge! !BEER
Hips.... Hips.... Drank the beer in one go {dizzly in my head} Thanks for the great feeling 🙃
