It's most likely the way AOL works.

I assume you're doing this through a web based news reader and not
using a client program like Outlook Express?

How come a lot of the times when I post a reply it doesn't show up
as a part of
the thread? It will show up as an to the original post but not
as part of
the thread. Sometimes it will be part of the thread.
It must have something to do with the way the preceding posts in the
thread
were saved. I'm reading and posting through AOL.
