Must likely because of age of threads would not be current and because of changes to link sources the links may not work in some of the threads.
I have been correcting allot of links in threads recently because Newmar is moving things around in
COM_NET most of them I have already corrected in the QT's links but that does not change them in the original threads unless I come across them.
I know now where the new ones are so easy for me to change, that's why I have stated go to the QT links the new links will be there.
