Needless to say, yes, we do. But I'm almost 100% certain that we, in general, don't. (You can always tell if I do, I leave a bracketed message with my name in it.)
I have on a rare occasion only to fix a strong mistake like listing Thran Lens instead of Thran Foundry. I haven't been putting in a notification mainly because I was trying to change a post before anyone else noticed the mistake and thus so the person wouldn't be caught on it.
Ok then Zadook, could you go to the Insomniac!!! thread in the Battle Arena and edit Tyler's post so that it stays within the boundaries of a normal screen?
