Hello,
In some communities people do not appreciate showing their full names on forums where they exchange, i would like to suggest having an option (a premium app), to let people choose to be "anonym" but with a pseudonym on discussions of forums they prefer, some thing like the actual anonymous check case but with pre-defined pseudonym.
Instead of posting anomymously (which is not good all time), the member can choose where to show his real identity and where to show his online-pseudonym.
consider adding a custom field to add intro ES profiles where members can pre-define their pseudonym.
voila !
