Hello @windfield, 
Thanks for your post. 

If you want to delete your Strava Community Hub account, please note that you cannot personally delete your Community Hub account from the settings. You can turn off all Community Hub notifications and log out of your Community Hub account. By doing so you will no longer receive any notifications or emails but can still maintain your account, just in case you ever want to use it in the future.

To adjust your notifications and subscriptions, sign into the Community Hub, then select your Avatar on the top right of the page and select "My settings".  From there, select the "Subscriptions and Notifications" tab, then go to "Notification Settings".  

 If you prefer to have your Community Hub account deleted, please contact the Community team at stravacommunityhub@strava.com
