I was thinking of this same sort of idea at one point. A separate chatlog for server wide chat/shout across all zones. I think the LS is originally meant to have people pass on what is going on in shouts for people looking for stuff, but sometimes this type of thing isn't reliable to get across. I definitely think a new chat feature should be implemented if possible to get across event gatherings to everyone but there should certainly be restrictions. Of course you should be able to filter/turn off the chat function if need be if you're in the middle of something and do no want it to be a bother, but another good restriction to avoid spamming on this chat feature is to maybe to put a time restriction on it so that you cannot make another chat on it for maybe 3 mnutes or 5 minutes max. People can send a /tell to that person if they want to hear more details and the spamming can be left to shouts (even though spamming in shouts shouldn't be done anyways).
