2) if you don’t have a diigo account yet, we can auto-create a new diigo account for you:

After associating your other credential with your Diigo account, you will be able to login with your Facebook/Twitter/Googl ID/Yahoo ID.

Btw, another frequently requested feature:  “can I change my username?”   Yes, now you can!  Login first then visit https://secure.diigo.com/setting to change your diigo username and/or password  (note: min 6-character username restriction still applies.)
