I have to admit, despite carefully reading everything you have written so far, I find you making increasingly less and less sense.
I have to agree with you on this one
And, this makes absolutely no sense: "My user name was encrypted with 2 or 3 special characters that have since become obsolete, and taken offline by ibm"
It's because of that sentence that I suggested the above sources showing various characters. When he said that the characters became obsolete, I thought they can no longer be found on most standard keyboards. OP might be talking about something else entirely.
