I agree with Rigwyn. This advertisement was this person's first post. It might be different if it was someone who was more known and experienced in the PS world and forum. It's a good idea and all, but I wouldn't do it unless I knew that this was an actually PS player trying to help others rather than someone who's doing this to advertise their service rather than RP. Also, as Rigwyn said, it would bring in people who don't have any interest in RP and just want to learn English, which completely defeats the purpose of PS. Besides, I'm a native English speaker, so I don't need it.
