Pokemon Go players will soon have the ability to suggest new PokeStops. Developer Niantic has announced it will be rolling out a beta for a PokeStop nomination system--but you'll only be able to participate in it if you live in a specific region.

The PokeStop nomination beta will initially only be available in Brazil and South Korea. Moreover, the feature will be limited to players who've hit Pokemon Go's level cap, 40, further narrowing the list of potential participants. Niantic says the beta will expand to other regions--and potentially more Trainer levels--"over time," but the developer hasn't announced any further details beyond that.
