So, I just thought I'd pick up PRO and see how I like it. So far it's been pretty good, got myself a charmander, caught a spinarak and a pikachu. I haven't really encountered any issues apart from the servers crashing. There are some questions I have though, that I couldn't seem to find anywhere else. 1. I know members can catch some Pokemon early. What does this exactly mean though? I want to obtain a litwick, but as far as I can tell, there's no place to catch it in the wild. There are other Pokemon like this too, like Spiritomb and Axew. 2. If non-members can't catch these Pokemon, can they obtain them from members through trading?
