How to make Posts show at the bottom of a discussion

Hey guys. I am having trouble with something, so hopefully you can help. First of all, I made a Forums. And when I make a topic and someone replies to it, their post always shows on top of mine so I need the first post to always show at the top and not the last. Thanks, and if you need more details, I'd gladly see what I can do

Hey try this

Code:

ACP/Forum/Categories and forums/Modify a forum

'Sort the posts of a topic by'

Thanks, that's all. This topic is solved and is able to be locked now.
