As you see in the screenshot below, there are tons of members here who have the name (null null)!
This name doesn't make sense at all!
What's the problem?
I can imagine that those members left the text blocks of the first name and last name blank when they registered in the community, so they got that name!
But should not the first and last name be compulsory?
If you allow some people to register in this community with an anonymous ID, it is best that their names are anonymous, not null null!
