Described here: Play Money Tracking
This would be a very welcome change allowing players to play HU grudge matches without paying rake.
It's a common problem now regs want to play each other for real money HU but don't want to have to pay rake. The only problem is HEM won't track or have a HUD for play money games. Is there any chance you could tweak HEM a bit to allow play money hands to be imported/tracked so this could be done? Then money could be escrowed or if they trust each other agreed to be shipped at the end and people would save a ton on rake.
