Suppose you wanted to report an entire thread, and not just one post in the thread. Is there a way to do that, or do you have to choose a post in the thread?
Just report the first post in the thread, and tell the mods why you did so.
Probably just report the OP if you felt it needed to be moved or closed.
on the other hand you could just click the report button on message #1 and state your thoughts.
As has been said, just report the first post and explain that you are reporting the whole thread.
No.
Yes, you do.
Thanks, all.
Now I want to know what thread!! 
I don’t remember if I was thinking of a particular thread. It was just a general question.
What if you want to report the whole of the SDMB, all at once?
I’m thinking about reporting the entire Chicago forum. Those guys and their sneaky Illinois tricks.
I’m reporting all of you to the hall monitor.
There’s a mod to contact about mass bannings.
Surely, you’re not suggesting that [DEL]Mar[/DEL]… I mean… one of the fine, upstanding MODs, here at the SDMB, would [DEL]stoop to… accidentally[/DEL] do such a thing.
Are you? 
No, um, I meant banning mass. I thought one of the mods had a missile that automatically homes in on the nearest place of worship. Yeah, that’s what I mean.
Only the Catholic threads.
Nice save. 
I want to report this thread.
Reported!
You haven’t a clue, boy.
