Broheim is also good for including the Mordheim Community status ratings. 1A means GW official at the last rules review, 1B means GW published but not official, 2 means non-GW but well tested by trusted sources, & 3 means Experimental.
But yes, treating everything as 'House Rules' & just agreeing in your group what gets used is the best thing. There are big chunks of the last rules review I don't like, so I just ignore them, but then I'll pull in bits from elsewhere... Whatever's most fun.
