Hi,
I've found a Forefox add-on called CheckPlaces which goes through your bookmarks in order to find sites that no longer exist.
Problem is that it looks at say
http://www.cableforum.co.uk/index.html and finds that the absolute page does not exist but obviously
http://www.cableforum.co.uk does.
Are there any good tools which will weed these out and give correct results?
