First I would advise you not to say anything regarding the specifics here, and certainly do not admit anything. You don't know who reads these things. IP addresses are traceable after the fact (records of the addresses and the postings are kept, even after they are deleted). My questions below are rhetorical, I wouldn't respond to them here.
Are you committed to the agreement? What are the advantages of taking it?
If I were you, I'd want to fight it. The way you describe it, it sounds like a misunderstanding or that, at the very least, you could argue it that way.
What exactly did the dean tell you? Did they threaten to expell you if you don't take the agreement?
Also, I would get a real lawyer's opinion about this. This is not a small deal. You're talking about something that will seriously affect your career, any way you look at it. You don't want to make the wrong decision. I certainly wouldn't take the agreement until I've talked with a lawyer.
Well I actually haven't negotiated the terms of the agreement yet, the Dean was just pushing me in that direction (she was actually talking to as if I was f'in guilty which was irritating as hell). She did say that watever the terms were, there would automatically be a note of the incident (of me "taking responsibility") in my perm record that would be sent to the bar. And I technically already made an "admission" to the Dean, I just told her the truth. I told her that I didn't do anything intentional and that I didn't cheat whatsoever. I didn't want to go in there "lawyering" her and asking if what I said would be used at the hearing, b/c I honestly thought she wouldn't even go forward with the charge once she heard what happened.
I'm just nervous about how fair these proceedings will be
I will def contact an attorney...
