Two nights ago, I completed the moving of all my GMail to my iBook G4, where it will be sorted and a subset will be moved to my fastmail.fm account. It had gotten quite slow and kind of unreliable. This morning, I couldn't get access.
I currently have the GMail account forwarding to my fastmail.fm account, but not deleting mail so I can catch the few straggler accounts where the gmail address is my preference/id.
So I will be primarily be using my GMail address as a forwarding service. GMail likely does not mind much, it still provides visibility for their service while not having to keep my stuff.
