[Wikipedia-l] Members?

[Merritt L. Perkins]

Please forgive my ignorance.
1. Are there members?
2. What are they members of?
3. How do they become members?
4. How do they know that they have been accepted?
It seems that when a person becomes a member he should receive a
membership certificate. This could be something that he can download and
print out to put in a frame and hang on the wall. It could have a fancy
border.
I haven't seen any information about this.
