There is something a bit amiss with the comments function - (I don't have any control over this, it is cut and pasted code and hosted elsewhere) - sometimes the link isn't there, and if it is, the number in the brackets (which indicates how many comments there are) is reading 0 even when in fact comments exist...sorry, I can only hope that the people at YACCS sort it soon...if you want to see if anyone has made any comments, click the link If there - click refresh if not) and if they are there, you will see them (I should say that in the light of recent events, some of you may be best advised not to bother...), and of course comments can be made in the usual way if the link is there.
