In response to Nigel's post I also have to say please don't knock Rita.  I was for a time a moderator on this forum and in the end the brickbats I used to receive made me realise that I did not wish to continue.  I wonder how many of you have ever moderated a forum or would even bother to put yourselves forward.  At times it is certainly no bed of roses, everyone ready to throw the mud but never ever any words of thanks.  So to Rita I would say a very big thank-you for being able to do such a good job and for holding your patience with those so eager to throw stones. 
Keep it up Rita.   :)
