Change your mail settings. Your missing Standard Members

Im only a standard member. Not sure if I want to be a premium member yet. I send email and the other member cant see them because they have mail setting set to not accept Standard Member email. I check my mail settings and it was the same way. I cant get anyone to get my mail so how am I supposed to know if this is a good site to join. It just took so long to decide to come here in the first place and then find that it is just me with a giant wall around me.
