Chris Heisenberg’s List has been ongoing for years. It’s pretty on the money-sometimes the years are off.

If you follow Ben or Forch on Twitter they will re-tweet or like commitments. Also you can follow “puck preps”, “hockey commitments” or someone like Mark Divver who has his pulse on all things New England hockey better than anyone. Mike McMahon is great too.
You can also go to individual players social media accounts to get updates but that’s less informative (until someone removes their commitment like Montgomery did a few weeks ago).
Lastly, I check junior league sites regularly for stats updates/scoreboards. Majority of guys are in the USHL, BCHL, or NAHL. Maine’s Elite Prospect page has current and future players as well.
Hope this helps!
