Even if anonymous posting wasn't 'banned', I don't think it's really an answer. I can't recall 'successful' anonymous posting in any internet forum, of the non-trolling sort.
Still, I sense that even the main site is crumbling. The song ratings page is corrupt (i.e. missing the song names), as is the chart watch, aka Dara's Chart Watch (linked to in the former), which mysteriously has the word 'minge' tactfully added to the foot of the page. If spam, or whomever, has infiltrated even the most mundane text-based pages, then does that mean someone has a password? I sense our hours are numbered.

Herding TWers into a new forum would be like herding cats.
Right. I think that if TW should unexpectedly disappear, BWW would be the natural refugee camp. Any attempt at re-setting up TW, or a TW substitute, should be initiated from there, possibly poaching the best BWWers while we're at it. A new messageboard would have to be set up properly under its own domain, i.e. not part of conforums or any of the other 'free' messageboard sites, which come with their own restrictions (both in terms of storage space, and of a baseline level of activity required to avoid the forum being deleted).
