citation problems

[Ragnar Beer]

Howdy!

I'm trying to meet german psychologists' formal citation requirements 
and have two problems/questions:

- When a reference occurs in the text for the first time all authors 
must be given. Later if a text that has more then two authors is 
referenced again it must be cited as '(Author_1 et al., 19xx)'. Is 
that possible in LyX?

- LyX uses [sqare] brackets for bibliographical references in the 
text. Is it possible to change that to (round) parentheses?
