Is the new rakeback system in place?  If so is there a minimum you have to rake in order to get something back?  It's advertised on the website and I've played probably a few hours worth of micro tables in the last few weeks but never received anything back despite being in the 12% tier.  If it's being advertised but isn't in place that's really scummy.  If it's not in place yet but the old system was eliminated without anything replacing it in the meantime that's almost as scummy.
