Helium Marketplace article purchased

I finally sold an article on Helium Marketplace: How the stature of the horse creates opportunity and obstacles: Movement. The money for this was quite good, almost enough to make up for the several articles that were not purchased. I hope to try again with this publisher, and maybe they'll like my work enough to ask me specifically to write more for them. Maybe not, but there's always hope! I don't know how much more I'll do for MP unless the titles are really intriguing, easy or well paying. It's a lot of work to just earn pennies if they aren't purchased.
