Hrmm .... This topic of chat and forums is difficult at very least.
So many thoughts and opinions, Ideas and comments I could throw out for all to read, but a friend has helped me learn something to consider as i type this so...
To not go to chat from a state of fear or dislike is to allow oneself to be intimidated.
To fear your comments being used against you from one place to another is truly devious.
To have to watch those you assume to be friends because there are sides to be taken is troublesome at the least.
To lack consistency in having written rules, and rules that you find out as you cross them and become banned is rare on the net but happens.
We all have to abide and enforce unwritten rules on ourselves and others.
I do as well. It is not a thing against anyone. The difference is on the level and importance of the unwritten rules and how they are applied.
Unless the unwritten rules become such a thing as to have importance enough to get one banned, if it does, then it should be written.
