Langlands group vs Langlands dual group

There is something called the Langlands group, so this article should refer to it. The common name for the Langlands dual group is simply the L-group. I think what is currently here should be in an article called L-group, and the article Langlands group should be about the Langlands group of a global/local field which is a (conjectural) extension of the Weil group of a global/local field by a compact group. See for example the nice article of Arthur's http://www.claymath.org/cw/arthur/pdf/automorphic-langlands-group.pdf . Any comments? RobHar 23:35, 4 September 2007 (UTC)
