Giving What We Can's My Giving functionality has been incorporated into EffectiveAltruism.org.
If you were a My Giving user, your data was migrated to EffectiveAltruism.org in late April 2018. You can use the same email address you previously used on Giving What We Can to log into your EffectiveAltruism.org account, but you will need to reset your password. If you already had an EffectiveAltruism.org account, your data will have been merged into that account.
