they don't namechange!
(well, Pan excepted, who is a flighty thing, but hey)
It's funny, as DH and I have previously discussed how useful the namechange thing is for mners- as it freely allows you to ask advice on topics that would otherwise completely embarrass or freak you out. On most fora, you cannot namechange (unless you register a 2nd, or 3rd account sock puppets ahoy!) but as I pointed out to DH a lot of the real usefulness of mn comes down to the fact that it can be truly anonymous if you wish it to be, and despite recent issues, I think it is a real strength of mn.
DH always uses his own name on the forums he frequents, though he does use them in mainly a professional capacity. I find this astonishing, not least because he has a unique name, (as do I) but then he never posts frivolous or inflammatory remarks.
Dads of mn... why do you not feel the need to namechange?
