I don't think I would like it, personally.
If we start with sections with different rules, it's going to become a damn mess quite fast. People will start to ask other sections with their own set of rules since someone got his own here and complain that it's unfair that some can and some cannot.
It's not the Ember subforum, it's just a subforum that I think could be warranted or perhaps maybe even wanted by some. ( I dont think I'm the first person to suggest this.)
That's mostly for reasons similar to what Anslo explained above that I would really fear such an initiative. It's like suddenly giving guns to chimps (sorry for the comparisons but are we so much better than chimps at times ?).
A lot of members are already unable to control their basic, entrenched emotional urges even with this polished and strict environnement. Why would it be better in a relaxed one ? Chatsubo is the proof it did not in the past.
Edit : I will review my opinion when there will be no more than 1 catacombed post per month. Of course, that moderated post will have to be done by mistake, not intentionally. And of course, I do not count the possibility where everyone got banhammered out of the forum so that nobody posts anymore (<- I see you coming, smartasses). I challenge all of you to prove me wrong by doing so for a few months.
