Thanks, Porcher ji,
"Given that my favourite topic (I am aware that plant names are boring for most people) generate little reaction from the "silent" majority, I wonder if there is a way of sending some messages to all the moderators at once." -> I think if it's resurfaced, then we may expect a few reactions. It certainly requires a lot of patience.
"If I can only post discussion starters in the usual manner, is there a limit to the text size?" -> It is set by google groups. I think the mail size limit now is 100 KB.
