Ryan, this is something that YOU can control... When logged in, click on User CP, then Edit Options, then Thread Display Options, then Thread Display Mode. There you will see four options to chose from. Most people set it to Linear - Newest First, so they can see the latest post first. Or you can change it to Linear - Oldest First. Here is an explanation.
However, I do not know if this will reverse what you see when you are NOT logged in. But if you ARE logged in, and have it set to Linear - Newest First, then you should see the newest post first, and the very first post should be #1 at the bottom of the thread. If you need further help give me a call at 210-674-5781 and I can talk you through it.
