FX Autotrading gets so little activity, why don't you just fold it back into Autotrading? Broken out categories should reflect demand, since space is precious. the 2nd thread was last updated on 2/14 and the 3rd on 2/10.
FX AutoTrading forum is less active, on average, than some of the others. However, the reason for the gap you mention is simply because that forum was not up - invisible and inaccessible by link - from mid-February until a couple of days ago. http://www.elitetrader.com/vb/showthread.php?s=&threadid=117996
I was going to roll the FX AutoTrading forum back into the Automated Trading forum but we had a company inquire about sponsoring it, which is why it is still up. If the potential sponsorship falls through, I will definitely transfer everything back to Automated Trading.
