I know there's probably threads on this already, and it should probably be in site discussion but nobody looks there.
I was having problems posting pics in threads and no one could figure out why. It also seems like there are a lot of people having this problem since they redid the site.
So for all of you computer illiterate people like me:
TURN OFF THE FANCY TEXT EDITOR. it is under My NS > Account Tools.
This should solve all your lifes problems, except for that burning sensation when you pee.
