Actually, the whole 'new posts' thing doesn't work very well. If a new post comes in while you're looking at the previous new posts, it 'wipes the slate' and only the one that came in while you were on-site still registers. And this happens even if the new post was made by you! I have no idea how that could be rectified.
(Edited) Well, it hasn't wiped it clean today. Twice it's retained the other new messages in memory after I've posted. Must be a phantom problem. (And I see there's a new smiley!:[ )
Isn't editing better than posting twice?
I do notice, though, that when messages are edited they don't show up as 'new' and notifications aren't sent. This means that corrections don't circulate as widely as the original mistaken posts.
How like the local paper!
