Or at least, for the love of sweet baby Jesus and all his chickens, read the OP's posts?
Especially if it's a long thread which may, you know, have moved on a little since the first post?
If you're so lazy and unengaged that you can't be arsed to check whether the OP of eg: a 200+ post thread in Relationships has added anything or updated their situation, why not just consider scrolling on by?
Cheers.
