This is implemented, under testing, and working fine so far. Now what remains is to decide the block number for the hard fork (around 135000?), generating all the binaries and issuing alerts for everyone to upgrade.
Great!
But maybe for the sake of obsessive compulsive disorder, would it be possible to tweak the difficulty numbers to have rewards be 45 & 1485 ? (ie. round numbers)
Or even 45 & 1500 (with extra superblock difficulty), wouldn't affect network velocity much, but would be neater to look at and announce

Difficulty is a number with many decimals anyway, so extra tweaking on the difficulty numbers will have no psychological impact, but having weird reward figures might ^_^
Could consider as well adding post-fix to the difficulty numbers with KB, MB, GB, TB, PB, etc (as in Kilobyte, Megabyte, Gigabyte, Terabyte, Petabyte) of expected storage size needed on the prime number - it can represents all or just a single prime number itself at the given difficulty found by Riecoin project thus so far. The post-fix serve as indication on the frontier digits-size of prime numbers the project is presently venturing.
