I have, twice. Now three. And you'll keep going until I'm bored into submission so I intend this to be my last post on the issue. You seem to have immediately got your knickers in a twist about the appointment of someone before you've even had chance to see what happens. The tone of your posts on this thread, and to be honest most others nowadays, is very argumentative. And as far as exchanging views on a forum is concerned I'm sure that IS an issue for some other people.
If you want to retire then return to the forum for the umpteenth time, complaining at the way it's run, then it does beg the question why you bother. And that's why I comment on it.
In answer to your subsequent questions I suspect the original posters have gone from here for the same reasons that they do from most forums. Many will have packed in trading, many will be bored with the same old questions. I'm sure the moderators have gone because they grew tired of being hounded for the way they moderated.
