Is "not remembering" the same as "no longer know"? [closed]

Solution 1:

"I no longer know" can mean something other than not remembering. If I'm at work and I haven't contacted a group and they have new members and new procedures I would say.

I no longer know how to get in touch with them or send them a request.

This would imply not that this item is no longer in my memory, but rather other circumstances outside of me have changed.

Remembering in contrast implies only my own memory. So should I say:

I don't remember how to get in touch with them.

I'm referring to myself as the thing that has changed not anything around me. I'm the one who has forgotten the phone number, email, or process involved.
