Change Forum Thread Post Order from Top to Bottom?

I am used to reading threads in other forums from top to bottom. A top to bottom order makes it easy to see the original post at the top of the page, to determine whether the question applies or is interesting.

Here at Host1Free, the forum threads are arranged in bottom to top order. This unusual order forces each reader to scroll to the bottom of each page in order to read the original post to see what the thread is about.

Is there a way to arrange threads so that I can read the sequence of posts in top to bottom order?
