I'm trying to get my head around how people landing on a question page will offer an answer.
I liked the promotion of Q&A that it would allow anonymous questions and answers.
Now I understand what "Anonymous visitors can also post question and answers, which will be published after they have successfully logged in. This lowers the barrier to entry, helping your community to grow faster" means - that users will see "submit and login" as a button and then hit a barren looking Wordpress Login screen.
This seems to me to actually make it much much too hard for people who don't already know wordpress user login system to pass by and contribute something.
Anon users will see their answer disappear and hit the wordpress logon.
All a bit grinding I think. No idea for them where their question went, how to register etc.
