Just to be clear, I'm trying to understand the purpose of labelling a group "virtual." In other words, what is that supposed to /mean/ in Gnus-land? The "holding the results of the nnir search" part of your response is not particularly relevant to the question, since that just happens to be the case for this particular "virtual" group. So I'm left with virtual == temporary Is that really all it means? >> The context for my question is >> http://article.gmane.org/gmane.emacs.gnus.general/82136, where I'm >> wondering whether it's OK to label "nndoc" groups as virtual > > Well,... I can't answer that. I think only someone who understands the intended meaning of "virtual" could answer it.

The question is,is there a reason that gnus-warp-to-article only does something in groups marked "virtual," and if so, what is that reason? >> * Should I be doing something different in `gnus-goto-article' to build >> a group with my message in it? > > I can't answer that either.
