I got those numbers for you.
2018 - 379 contributors.
2018 - Most Deals: [mention]BostonCharlie[/mention] - 658
2019 - 227 contributors.
2019 - Most Deals: [mention]TheJohnP[/mention] - 1,531
The drop in contributors year to year is to be expected, but when compared to the "population" (member size) of the two sites, MoT's is well ahead of WUS if based on per capita.
