Mark Evans is the kid Dudders and his gang beat up at the beginning of the 5th book. It was a mistake by our Jo to name the victm 'Evans' (she says) because Lily's surname was Evans before she became Potter. Thus heaps of speculation - " did Harry have cousins?" etc - came with this Jo-stuff up. Jo ended up having to come out and state "Mark Evans is no-one" therefore making it THE most sought after posting name. Well 'the most sought after posting name' after Squidward which is the name she said she would use if ever she did post on these chatrooms.

In answer to your question 'Does Jo read these postings?', I like to think Jo's watching over all that I do........ then I could sue her for stalking
