Yeah, something like that. You have a stat that includes the number of posts in the forum for each user with a ranking system based on that stat, perhaps having a similar thing for the scenario section or even integrating the two. The stat would be shown in the scenario section, and would include posts in the forum and also in the scenario section.
Having separate stats for the number of scenarios submitted might be a nice thing to have, to disaggregate the numbers and have several stats next to the user name and avatar would be a nice touch. I am aware that this might not be possible and that it might take more of your time than other priorities. Thanks.
