Administrivia: The amount of spam comments submitted to this site overwhelms the legitimate questions asked (Note: not all legitimate comments are made public). They are being submitted by spam robots - the titles and names of the posters usually make no sense. The standard practise is to select all and delete, so real comments are often caught up in the pages and pages of fake comment. We are investigating a good spam plugin to add onto the site to cut down on the amount received.
