I am thinking of using nnagent.el. The thought is to make gnus-agent-covered-methods more flexible (or introduce a new variable) so that gnus-agent can be customized to cover only retrieving headers for some servers. Moreover, users could be benefited from gnus-agent without switching between plugged and unplugged, i.e. a more transparent agent implementation. However, it is just a thought. I can't implement it in a short time. Any comment? ShengHuo -- (setq gnus-posting-styles '((".*" (signature (format "(setq gnus-posting-styles '%S)" gnus-posting-styles)))))
