Well, Take it from me, a veteran who was around to see the T-Dome founded, and disabled not too long afterwards...The T-Dome was no better than the smelliest armpit of the internet known as /b/.
The trolling, flaming, and general disrespect was rampant and having a mature discussion/debate was impossible thanks to the little kiddies who'd just post a wall of insults to anyone opposing their viewpoints. Needless to say, the censor was often pissed on so many times, it's a wonder that the T-Dome lasted as long as it did. It was, admittedly, part of PC's shameful past, just like the first and second reputation fiasco was.
With all that being said, I would support the comeback of the T-Dome if it weren't for the fact that this forum is simply far too immature. There are far too many kids who would likely register a new account under a proxy, sockpuppet their way to the required number of posts and gain access to the T-Dome just to piss and **** all over anyone who disagrees with them, because they lack the maturity and paitence to conduct a calm, intelligent, and mature debate.
Now, theoretically, one might argue that a veterans only requirement (People who've been here for 3+ years) could probably seal out that danger, but keep in mind that even us veterans aren't always mature, and the section would either repeat it's own history and burn down, or it'd just collect dust and rot away from the lack of people to post in it.
Either way, the entire idea is hosed, simply because it's not possible to enforce the level of moderation necessary in there without forcing all threads/posts to be moderated. We'd need like 10 or 15 moderators for that section, to ensure timely post/thread approval in order to keep discussion moving at a timely pace. Not to mention, that selecting that many moderators at a time could take an insane amount of time, since moderation of this section would require maturity greatly above and beyond what is typically found in members nowadays. Additionally, all the veteran staff members are burned on the idea. Getting their vote of approval on this would be more difficult than getting blood from a turnip. X3
