This whole issue is a problem of t2w's own making. Everyone knows the background, so its not worth repeating other than to say they are sowing what they reaped.
It took 2-3 years of hard work to reach this position, and it'll take 2-3 years worth of hard work to get to where they want to get to next (assuming they know where they want to be, and from what i see day in day out, there's no cohesive vision of where they want to be, and policy often changes 180 degrees within days)
Private threads by their nature are not inclusive, t2w can't promote them and derive little benefit from them, the people participating are not really the demographic their advertisers are targeting etc etc. if a private section becomes successful why would any of its members bother posting on the public forum ?
Seriously, if people want to post about trading, why not post some place that's its encouraged ? Big mikes is probably the obvious candidate, but even traders laboratory or baby pips at a push would provide better moderation and keep things on track. Alternatively start a free forum and invite people to join.
Time and time again t2w staff use the tired old excuse that the members set the tone. I'm sorry but its a complete abdication of responsibility, and indicative of the lack of direction and vision.
I'm probably being harsh, but its true. They are acting like an inexperienced trader desperately holding onto a loser hoping it'll come good... After all, It usually did...
