Can't find a FAQ on Ignition but Bodog is the network so obviously this applies to Ignition.

Rake Changes

Rake will be collected at $0.01 for every $0.20 in the pot, instead of the previous $0.05 per $1.00
Max rake will be moving on Heads-Up Tables from $0.50 to $1.00
Max rake will be moving on Pot Limit and No Limit tables at stakes higher than $0.10/$0.25 from $3 to $4
Rape those micro players some more so they can't move up that easy but doubling the heads up table rake is ridiculous.
