Enjoy the con. I'm sure if you don't intentionally become a part of your own problem again, ie, intentionally confront anyone involved and/or stalk her, it wouldn't be a problem. If they confront you with issues, handle the problem maturely and if it calls for it, report them if they're harassing you. That's it. Otherwise, ignore the problem altogether.
As for people continuing to make comments, and people making idiotic remarks like Joecool's... welcome to the internet. I advise you to grow a tougher skin both here and in real life, according to what you've said in your posts. The internet isn't here to offer you sympathy whenever you feel like you need to whine about your own personal drama. It'll make you feel better when it's present, but probably won't aid you in any way. Eventually, if you're an idiot in your posts, someone will point it out.
Anyways, to lock the thread, scroll down to the very bottom of the page and there should be a tab on the lower left corner. :T
