I had the same problem with not remembering which chars were on which account. When you try to put in the char name, if you get the wrong name there is a link that says File a petition or something like that. If you send one in just tell them youre trying to come back to the game and remember your uname/pwd but cant remember the char names. They emailed me char names for 3 of my accounts. Got me past that step.

Im interested in getting mining together but honestly it will have to wait til I head to 0.0 at some point. I already destroy belts and its going to get even worse... so high sec mining cant really sustain too many miners.
