I, get what you are saying Bob, Now for me there is no problem I type slow and I spell check (using Hot Lingo) most of the time. But evidently their are some hot fingered people on here. What they are saying is that one person will say something that gets the second person up set. The second will type a hot reply back. At this time the first person will go back and change his message, to a nice message, and the end result is that it looks like the second person attacked the first person.
There is a worse possibly that could be going on. If you have any ex submariner they can agree with this, on long crews we get bored, very bored, and we start playing games with people. Take three people, two don't like each other, the third person appears to be a friend to both. He tells one person one thing and the other person the opposite thing, pretty soon these two people, have gone from not liking to hating each other. Mean while the third person is having a good time watching the show. The only way to calm down the situation is to get the first two people together, and get them to comparing notes.
