Although a promising title for a topic, the quality of the answers given and thinking behind them is pretty dire.Managing a round properly is what sets people apart. A few people have mentioned how a round becomes a monster, some have even sold it or walked away just to lose the burden, so managing it properly is key to both hanging onto your sanity and stress levels, and equally important, maximising income while minimizing effort.
My view on this is that owning software helps, but this is not in itself round management.
