I know I can't open an e-commerce or something similar in wp.com and I can't use other ads but I've seen a service with an e-commerce hosted with their platform that I might be interested too.
So my question is: can I open a page and link that page to another commercial service? With another ads service too because it's hosted somewhere else? As I'm not sure I prefer to ask. It would be like having an external forum linked to a page with google adsense there. But it's a store.
The blog I need help with is italianeography.com.
