It's time for another re-cap!
Note: As with previous years, the query to find these threads was expanded to include ones that were started in Nov & Dec of the previous year, so as not to exclude hot topics that got started late in the year.
Notable this year:
- It seems like modding activity was generally down in 2020. (I'm guilty of that -- sidelined by non-automotive projects.)
- More than a few longtime members have become YouTube creators, and dropped by to share/promote their ecomodding-related videos.
- 2020 was the first year that a build thread was so active that it appeared on two years' lists! (M_a_t_t's Mercury Tracer project)

He's since sold it and
bought yet another one.
