How many posts till it moves to another page?

I'm currently on the 12th reply and getting tired of scrolling, is there a way to change it or no? or when does it even go to the next page?
Help, Thanks

i think on the 10th but you can edit it

um would you know how to edit it, i remember seeing it a while back but not anymore
cause im on the 24th post,lol

Yes I am wondering the same thing, I have a post that keeps going and going, and it doesn't switch to another page, how would I get the post to start making another page?

General>MEssages and Emails>Configuration
Posts Per Page :
If you set it up at 10, after 10 posts a new page will come up.

Hope that helps.
