From Hermione's experience helping Vaughn deal with his letters over the past few days, more than half of them were probably requests for collaboration or custom Potions.
People were always flocking to "authority." Some impatient souls didn't even wait for Vaughn to reply. They simply enclosed a Gringotts Bank draft with their letter, bearing a magical signature but no amount filled in.
Their generosity made Hermione stare.
Vaughn usually had Hermione destroy those letters, though. People who were that generous usually had something wrong with them.
Just under half of the remaining letters were generally invitations to contribute to journals such as Extraordinary Potions, or requests for papers, reviews, and experimental reports.
Whether in Muggle society or the Wizarding World, genuine academic luminaries were always in high demand with scholarly journal editors.

The official correspondence was more complicated. Especially after his "academic visit" to North America, several South American countries had joined the Wolfsbane Potion International Trade System. Since the start of the school year in September, C had been working to put that cooperation into practice.
