By all means, everyone...ignore typing and spelling, forgive what appears to be the occasional faux pas, and just enjoy chatting. For those of you who are new to it, never worry about keeping up...if you want to reply to something, just do it; if it falls a ways down the chat, or it looks like the subject has changed, don't worry about it. If you have a question, even if you don't think it "fits" with the current chat, ask it! If it gets missed, ask again, maybe it was just swallowed up in the text...I'm sure someone will try to answer you.
Rania, we've all answered an overlap at an inappropriate time, it happens when there are several conversations going on...no one would think you were answering a sad post with "wonderful", we know it isn't your nature. Sometimes it happens when the subject is changed in the blink of an eye, sometimes one persons connection is "lagged" so their responses come later than they type them.
I personally love the differences in slang and usage in different languages...they make for some pretty interesting chats! One year when our hospital was host to a large number of international nurses for several months, we compiled a "translation" manual..."knock up" was one of the ones we had the most fun with. In the UK apparently it means "wake me" so knock me up in the morning had a totally different meaning for our gals from the UK than the ones from the US! Even names for soft drinks demanded an entry...we could ask for soda, coke, fizz, pop, or soft drink, and all get the same thing.
