victor,
I'm reading all this and it's bugging me so I can only imagine what cyclone is thinking. To me, unless a person does something to warrant a ban, there shouldn't be one. cyclone or anyone else has no control over what others will do or say and it seems a bit unjust to exclude someone based on what might happen.
In any case, putting an organized weekend outing together isn't the easiest thing to do and no matter what, not everyone is going to be happy. The only thing that someone can try to do is get a bunch of people together that will have a good time without the drama.
