I thought Buddika and TrueCreation had a one on one debate in the Great Debate forum?
In any case, the forum rules are the same as before but previously there were many more creationists posting. It is hard to imagine that suddenly all creationists would chaffe at having to follow the forum guidelines. Bannings are few and far between...attempts have been made to get creationists to moderate...what's the fuss? Look at Terry Trainor's site where he just bans anyone with an opposing view.
If creationists are lurking and not debating that is their decision. If they are upset because many of us do not accept statements "like the evidence for god, ID, the tooth fairy are self evident" then the burden is on them to come up with a better argument and debate. Most of us are here ready and willing to debate anyone who comes onto the forum whether it be creationists, IDists, or whatever.
The concept of a one on one portion of the forum could be interesting but don't such things already exist on the net? And why go to a debate forum only to lurk?
