Danbi,

There is nothing for the stratum coders to assist with.  This is purely a Dev issue at this point.  Groestl stratums work period.  Diamonds implementation does not.

If you can take ANY other groestl coin (what..all three of them?) and have it work in a heart beat, which they do, its not the stratum, its the coin.

I've supported diamond and solo mined a fair amount of them, but starting to lose patience myself.
