| Welcome Naomi (belated I know)
A full stop usually means someone has edited and deleted the content of their post.
Greening (and redding):
If you look at the top right corner of any post there is a scales symbol.
If you approve of a post you can click the scales symbol and a box pops up. Pop your comment in there and you've just greened (or redded) someone
To see if you've been greened click user CP at the top of the screen and you can see comments made to you.
Cheers
