if I wish to add some strategic thoughts (not a full guide though) is it better to put in under an already existing (indexed) guide or should one make a new thread?
I'd rather create a new thread if I were you, and then try to get it referenced in the big strat thread that lists all nation strategies on the first post (through a mod I suppose).
Its more an update to todays CBM versions, after all, a number of guides count on Hammers, SDRs, Bloodsstones etc, but in some cases the adjustment can be quite minor.
