Singular: User. Plural: Users or Community.
There might be other nouns depending on users preferred activity, specific role (asker, answerer, reviewer, moderator...) or experience, (new user, ...)
Since Stack Exchange is not really a Social Media, it doesn't allow chitchat1 and each site has a very specific scope, whenever there is a call to action there is no need to use a nickname to address the Stack Exchange community as a whole.
