The most obvious problems with the authors' network are as follows:

1. There is no entry condition;
2. The minor speech functions are split ('express self' vs 'attending'), with the latter grouped with major speech functions ('negotiating');
3. The minor speech function 'alarm' is not accounted for;
4. The INITIATING ROLE system ('giving' vs 'demanding') is not named;
5. The COMMODITY system ('information' vs 'goods-&-services') is not named; but most importantly,
6. The INITIATING ROLE system ('giving' vs 'demanding') appears six times instead of once.
