(Ella) If you've got something to say, say it. And even if you haven't, still say it, be it ever so banal. This place may appear cliquey to the relatively infrequent poster but it isn't. Even if we assume it is, all you have to do is put up a few remarks and you'll be part of the clique anyway. :-)
