Something I posted in another thread:
"Just an FYI, you have 2 hours to edit your posts, so if you forget something you can always just click on the 'Edit' button and add what you forgot to say"

I would hand out cookies, but I've been ordered not to by the brat. Sorry
/me gives out muffins instead
