an editor ask for the possibility to auto-fill author meta data when submitting an article with the QuickSubmit-Plugin. So, he enters “Smith” and then suggestions for already known authors pop up (or something like this). Currently, I offered him a workaround by using an auto-fill browser plugin.
I asked that ayear ago or so and I have been told that due to some privacy regulations in EU and some other countries that is not possible.
So, fill it manually as I have done that.
Some legislations do not allow that author is by default easy to be listed and his/her details seen. That is my understanding. Probably there are cases/scenarios when this restriction is justified.
