I think it was kind of Robert Glyn Baker's ex wife to send him a cutting, which solved the mystery.
The fact she sent a cutting suggests to me (IMHO) that Mr Baker does not have a computer, otherwise why didn't she just send an e-mail?
As for RC not being mentioned in any of the articles I rather think that's down to the writers of the articles - or maybe the original article that was picked up by the rest. If they aren't a RCer or have read any of these pages then they would not have any reason to mention all the hard work everyone put in.
Who knows maybe one day some budding author will write a book on Ted's lost years and put in it how thousands of strangers from all over the world who go by the name RootsChatters help to find his Master.
