I have some suggestions to make the DM site more informative, and that will give the buyer a better understanding of the model he is supposed to follow:
There needs to be information on whether the model uses dynamic or Static Weight
It should be possible to see the model on the longest timeframe possible, even if the creator has only published it for the last 10 years.
**After seeing this discussion at Fewer parameters make better models. - #40 by yuvaltaylor, it would be great to have information on the number of nodes used in the model. I see that there are some of the DM models that are already giving out this information
