The admin email address is
[email protected]I don't think it's possible to delete your old posts, even if you no longer are a member, except by going back and deleting them one by one.
If you don't want to be contacted by anyone from here, then you can edit your profile to keep your email address hidden (or delete it entirely). You can edit your subscript
ion settings to stop receiving updates about
threads you have subscribed to, if any.
Most people who take a break from this forum or leave the forum just stop logging in. If that option doesn't feel final enough for you, then maybe the admin can help.
Really wishing you well, Sunflower!
