I tend to agree with Rich here. When splitting a forum, some common-interest content might be lost. I see no significant common-interest content here. If it's about Peru, it's not about other countries in South America. And vice versa. Therefore I don't see a disadvantage to the split.
Readers, please correct me if you think I'm wrong. The deadline to vote is approaching...
I think your point just turned the light on for me. I'll be voting yes.
