Excellent addon. It takes some time to run but this is necessary to do various tests to see if the URL is valid. This addon works perfect. Also an excellent and fast service. I have an 7 year old forum and its working no problem. Support from provided by the Coder is very good. I found over 116462 bad links in my forum. Thanks for this nice addon and thanks for good support. I am highly recommended this addon for Link based forum !!!
